The 60 years' evolution of power generation equipment has created an epic glory

editor's words: it has opened up the aesthetic picture of the 60 years' development of China's power generation equipment manufacturing industry, and the clank and arrogance of the equipment manufacturing industry in catching up, the great changes of the power industry in the 60 years' transformation, the continuous struggle of several generations of power generation equipment manufacturers, and the hope and passion written with sweat are vividly on the paper

looking back on the past eventful years, each acceleration of the development of the power industry contains the historical changes of China's power generation equipment industry. If the power industry is regarded as the heart of the national economy, the power generation equipment manufacturing industry is undoubtedly a blood supply system that makes it flourish. From "starting from scratch" to self-reliance, digestion and absorption of introduced technology, to independent innovation, optimization and improvement, the power generation equipment manufacturing industry has made a remarkable leap from scratch, from "weak" to "strong", and has also witnessed the economic and industrial take-off of the motherland in the past 60 years

60 years of spanning, 60 years of brilliance. On the eve of the 60th anniversary of the founding of new China, we will once again focus on China's power generation equipment manufacturing industry, carefully appreciate the evolution of the power generation equipment manufacturing industry in the development, listen to this magnificent music of the times, and look forward to China's power generation equipment manufacturing industry, which has stood at a new starting point, releasing huge energy again and making unremitting progress towards becoming a power generation equipment power

60 years, cold and summer come and go, with a flick of the fingers

On July 31, 2008, the National Energy Administration officially confirmed that unit 1 of Guodian Taizhou Power Generation Company, which was put into operation at the end of 2007, is a 700million kW landmark unit in China. Zhangguobao, director of the national energy administration, said, "as a million kilowatt ultra supercritical coal-fired power generation unit, unit 1 of Taizhou Power Generation Company has become a 700million kilowatt landmark unit, which means that China's power industry has embarked on a sound and rapid development path of 'high scientific and technological content, good economic benefits, low resource consumption and less environmental pollution'."

it seems that the applause that resounded in the Great Hall of the people is still in our ears, but China's power industry has once again sounded the rallying call for progress. On August 16, it was learned at the national power work conference that China's installed power capacity exceeded 800million kW, marked by the commissioning of unit 6 of Laxiwa Hydropower Station affiliated to China Power Investment Corporation

China's power industry is developing rapidly. In the five years from 2002 to 2007, the installed capacity of new power generation in China was about 350million kW, which was equivalent to the total of more than 50 years from the founding of the people's Republic of China to 2002, and also equivalent to the total installed capacity of three developed countries, Britain, France and Italy. Zhangguobao once said proudly, "this is not only a new milestone in the history of China's power industry, but also a miracle in the history of world power development."

however, the "miracle" shows not only a sharp increase in quantity, but also a qualitative leap. The rapid development of power industry has also brought vigorous vitality to China's power generation equipment manufacturing industry

after more than half a century of construction and development, China's power generation equipment manufacturing industry has continuously improved its ability of independent design and Innovation: it has the conditions and ability to mass produce 300000 kW oil source maintenance units and 600000 kW units; China's 1million kW ultra supercritical thermal power units and 300000 kW circulating fluidized bed power plants have basically entered the stage of independent design; 700000 kilowatt hydropower units have been completed by themselves, and the third generation of million kilowatt nuclear power units have been completed successfully. Behind the remarkable achievements is the arduous but promising road of China's power generation equipment manufacturing industry. Today, China's power generation equipment manufacturing industry, which is becoming more and more mature, is once again ready to go, making great strides towards a powerful country in power generation equipment manufacturing

[starting from scratch] witness the dust laden memory of "China's speed"

. Every hard or exciting historical scene has witnessed the 60 years of China's power generation equipment manufacturing industry. The power industry, which began in 1882, is perhaps the most typical epitome of it

figures become the most favorable evidence

from 1882 to 1949, China's installed capacity was 1.85 million KW. Even three years after the founding of the people's Republic of China, China's installed power capacity was only 1.97 million KW, including 190000 kW for hydropower and 1.78 million KW for thermal power

In 1990, the total installed capacity of the country reached 137.89 million KW, including 36.05 million kw of hydropower and 101.84 million kw of thermal power. At this time, compared with the 1.85 million kW in 1949, the total installed capacity has increased by 6899.49%, while the water and thermal power have increased by 18873.68% and 5621.35% respectively

In 2000, China's total installed capacity reached 319.32 million KW, including 79.35 million kw of hydropower and 23.75 million kw of thermal power. Over the past 10 years, China's total installed capacity has increased by 131.58%, and the water and thermal power have increased by 120.11% and 133.25% respectively. By 2008, China's total installed capacity had reached 792.53 million kilowatts, with an increase of 148.19% over the past eight years. The new total installed capacity exceeded the total of the previous 48 years (1952-2000)

In 1987, China's installed power generation capacity exceeded 100million kW for the first time. It was 38 years since the founding of new China

however, it took only 8 years for this figure to rise from 100million kW to 200million kW; It took less than a year to develop from 500million kilowatts to 600million kilowatts and 700million kilowatts respectively. Now China's total installed power capacity has exceeded 800million kilowatts

this is the speed of China and the world. Behind the rapid development of China's power industry is the subversive leap of China's power generation equipment manufacturing industry

since the founding of the people's Republic of China, after more than half a century of unity and struggle, China's power generation equipment manufacturing industry has experienced 10 years of establishment, 20 years of development, 30 years of upgrading and upgrading. Now it has overcurrent, overvoltage, overspeed, overload and other protection devices. It has been built into a power generation equipment manufacturing base with considerable scale, level and strength, with Harbin Electric Group, Shanghai Electric Group and Dongfang Electric Group as the main body. However, on the eve of the founding of new China, China's power generation equipment manufacturing industry is still basically in a blank state

In June, 1951, Harbin Electric Machinery Factory (hereinafter referred to as "Harbin Electric Machinery Factory") broke ground on the site of the original Harbin racecourse. In the same year, the 800KW mixed flow vertical water turbine generator set manufactured by Harbin Electric Machinery Co., Ltd. came out, which also marked the first step in the manufacturing of power generation equipment in New China

In August, 1952, the financial and Economic Committee of the State Council approved the construction of a set of power generation equipment main engine plants in Harbin and Shanghai respectively, and in 1953, Shanghai steam turbine plant (the former general machinery plant), Shanghai electric machinery plant (the former No. 4 electrical engineering plant) and Shanghai boiler plant (the former Pujiang machinery plant) were successively established. In 1958, designed by the original eighth Design Institute, Harbin Electric Machinery Co., Ltd. expanded the large hydropower manufacturing workshop and its auxiliary workshops, built large plants and imported and installed large equipment, and built Harbin insulation material factory. Thus, the first power generation equipment research and manufacturing base in the Republic was completed

in 1965, the expansion of Dongfang Electric Machinery Factory (hereinafter referred to as "Dongfang Electric Machinery") in Deyang County, Sichuan Province also began

after the initial completion of the manufacturing bases, the plants of Harbin Electric Group, Dongfang Electric Group and Shanghai Electric Group have introduced foreign advanced technology. Now Harbin Electric Group is developed from 6 of the 156 key construction projects assisted by the Soviet Union during the first five year plan period. At that time, Harbin power plants comprehensively introduced the design and manufacturing technology of Soviet High and medium pressure thermal power units and medium and small capacity hydropower units, and took hydropower units below 100000 kW as the leading product; Shanghai power plants have introduced the design and manufacturing technology of 6000 kW and 12000 kW power station equipment from the former Czechoslovakia, and gradually formed a product pattern dominated by 50000-100000 kW high-voltage and ultra-high pressure thermal power units

in the process of technology introduction, each factory also pays attention to the training of professionals in power generation equipment design and process engineering. It is through their perseverance and innovative manufacturing spirit, after initial imitation, each factory began to design independently in the late 1950s and produced a number of important products in a planned and step-by-step manner. Among them, in 1958, Harbin Electric Machinery Co., Ltd. manufactured and completed the first Xin'anjiang 72500 kW large-scale Francis turbine generator set in New China, the 50000 kW double water internal cooling steam turbine generator successfully developed by Shanghai Electric Machinery Co., Ltd., the 100000 kW hydrogen internal cooling steam turbine generator manufactured by Harbin Electric Machinery Co., Ltd., and the 25000 kW ultra-high voltage unit were all representative works of China's power generation equipment manufacturing industry at that time

it is worth mentioning that after the successful research and development of 230t ultra-high pressure boiler by Harbin boiler plant, China's self-designed and manufactured 50000 kW ultra-high pressure unit was also announced, which created a precedent for the independent design and manufacture of domestic power generation equipment and laid a solid foundation for China to establish a relatively complete power generation equipment industrial system with a certain scale in small countries such as Tanzania and the United Arab Emirates

[opportunities of the times] writing a new chapter on development in the process of refining

in fact, it was the repeated exploration and practice of power generation equipment technology in the 1950s and early 1960s that enabled China's power generation equipment manufacturing industry to have a strong technical foundation, and also painted a clear blueprint for its future development. "Although many difficulties were encountered during the period, the research and Practice on those technologies played a positive role in the later expansion of the power generation equipment manufacturing industry." An old engineer of Dongfang Electric told me so

in the following 60s and 70s, China's power generation equipment manufacturing enterprises entered the era of independent innovation based on the principle of "self-reliance and hard work". On the basis of fully digesting and absorbing the technologies of the Soviet Union and the former Czechoslovakia, the enterprise has made bold innovations and made repeated achievements in unit manufacturing. Domestic high head Yunfeng 100000 kW water turbine generator set, Liujiaxia 300000 kW double internal cooling water turbine generator set and air cooling units of different capacities have been born in Harbin and Shanghai

however, although China's power generation equipment manufacturing industry has made great progress compared with the early days of the founding of the people's Republic of China, it is undeniable that there is still a large gap between China's manufacturing technology, design and equipment at that time and the advanced level of foreign countries. How to catch up with the manufacturing level of developed countries faster and better and improve the design and equipment capacity became an urgent problem for China's power generation equipment manufacturing industry at that time

this time, a new era has visited China's power generation equipment manufacturing industry
