[Abstract]:Hydropower energy is green, clean and sustainable energy. By the end of 2015, China's hydropower installed capacity was 319 million kilowatts (accounting for 27 per cent of the global hydropower installed capacity) and generated 1.1143 trillion kilowatts of electricity. Compared with 721.02 billion kilowatts of hydropower generation in China in 2010? Time increased by 393.28 billion kilowatts? This benefited from the completion and commissioning of a number of large-scale and super-large hydropower projects during the 12th five-year Plan period. During the 12th five-year Plan period, with the help of the completion of a number of super-large hydropower stations, such as Xiluodu and Xiangjiaba, the hydropower power generation in China has increased rapidly, and the manufacturing technology of hydropower equipment in China has also made great progress. However, compared with the advanced level of foreign countries, there are still some gaps in the advanced control technology of hydro-generator set, intelligent hydropower station construction, hydropower big data analysis and data mining technology, which still need to be caught up in the future. This paper mainly introduces the mathematical model of hydrogenerator regulation system, discusses the application of intelligent control strategy in hydrogenerator control, and in view of the shortcomings of the existing power regulation process of No. 1 hydrogenerator in Daxia Hydropower Station of the Yellow River, puts forward a power regulation algorithm of hydrogenerator based on fuzzy adaptive PID, and carries on the step response and no-load test of the algorithm by using Matlab/Simulink. The typical experiments of three hydrogenerators, such as load rejection test, are simulated by computer. The simulation results show that the algorithm is robust and the PID parameters can be adaptive. The research results of this paper are of great guiding and practical significance for optimizing the control system performance of No. 1 hydro-generator set of Daxia Hydropower Station on the Yellow River and improving the efficiency of the control system. it is the research direction of intelligent hydropower station in the future.
