At present, main AC power systems of advanced fighters all apply digital controllers with microprocessors. The signal input and output circuits are vulnerable to the effects of electromagnetic interference, which may cause air-power-off fault. The paper analyzes the electromagnetic environment on the aircraft, discusses the airborne electromagnetic compatibility by comparing domestic and international contents and limitations of the electromagnetic standard. Furthermore, it proposes measures to resolve the electromagnetic compatibility
At present, pumped storage power station based on two-part system electricity price cannot effectively recover the cost in China, so it has become one of the development directions for the pumped storage power station to enter the electricity market and obtain benefits. Combined with the background of electricity marketization, this paper analyses the benefits of pumped storage energy in electricity market from two aspects: the electric energy market and the auxiliary service market, based on the functions of peak load shifting, peak-regulating, frequency modulation and phase modulation provided by pumped storage power stations. Efficiency analysis based on pump storage power station, an economic benefit, environmental benefit and social benefit for the primary index is established under electricity market environment benefit evaluation system of pumped storage power station, based on the G1 - benefit evaluation model of entropy weight method, taking Tongbai pumped storage power station as an example to carry on the comprehensive evaluation, the evaluating model is verified to have been put into production of pump storage power station in power market yield were analysed, and it provides the direction for future development of China pump storage power station is proposed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
