The Research Of Hydro Power Regulation Based On Fuzzy Adaptive PID Algorithm

Hydropower is a kind of green, clean and sustainable energy. By the end of 2015, the installed hydropower capacity of China is 319 million kw(makes up 27% of the world’s water and electricity installed capacity), and the power production is 1.1143 trillion kilowatt-hours, which makes up 19.9% of the total power production. Besides, the newest data about the total power production published in 2015, comparing to the recorded data- 721.02 billion kilowatt-hours in 2010, has increased to 393 billion KWH, these results are obtained under the benefit of many large hydropower construction completed and put into operation during the period of "twelfth five-year" development. With the construction of power stations such as Xi Luodu and XiangJiaba hydropower station, our hydropower generation has a great growth, our hydropower equipment manufacturing technology has made great progress too. But compared with foreign advanced technological level, our country must have a lot efforts to make in terms of Advanced control technology of units, intelligent hydropower station, the innovative development of hydropower and data mining technology.The thesis introduces mathematical models of hydroelectric power conditioning system, discourses the application of intelligent control in hydro generator control system, study an waterwheel generator power adjustment regulation based on fuzzy adaptive PID algorithm in order to slove the problem of No.1 hydrogenerator power adjustment process in Daxia-Hydropower Station. In addition, the thesis also emulate this algorithm by Matlab/Simulink, the simulation results show that the algorithm has good robustness, parameters can be adaptive.The research results can opmitize the performance of No.1 hydrogenerator control system, the efficiency of the No.1 hydrogenerator control system. More importantly, the research results have important guiding significance and practical significance, is the future direction of research on intelligent control system of hydropower station.
