Design and application of excitation system for Yangjiang pumped storage unit
Taking Yangjiang Pumped Storage Power Station with a unit capacity of 400MW as the research object,this paper first briefly summarizes the function of pumped storage and the basic situation of the power station,then introduces the design and composition of its excitation system in detail,and discusses and compares the special differences between the excitation system of pumped storage generator set and that of conventional hydro-generator set in equipment configuration,functional design and signal interface.According to the field actual test and verification,compared with relevant national and industrial standards,the results indicate that the design and performance of the excitation system of Yangjiang Pumped Storage Power Station can meet the operation requirements of pumped storage units.It can provide valuable reference and guidance for the design of excitation system of large pumped storage power station,and has important theoretical and practical significance for optimizing and improving the excitation system of pumped storage power station.
