Coupling Stability and Multi-Frequency Transient Characteristics of a Variable Speed Pumped Storage Power Station Under Generating Mode
Coupling stability and multi-frequency transient characteristics of variable speed pumped storage power station (VSPSPS) under generating mode are main topics of this paper. Firstly, the overall model of VSPSPS is established and the coupling stability analysis of VSPSPS is carried out. Then, multi-frequency transient characteristics of VSPSPS are revealed and the generation mechanism is clarified. Finally, the influence of active power regulation and speed regulation on stability and transient characteristics of VSPSPS is analyzed. The results show that coupling stability of VSPSPS can be characterized by a stable domain determined by the control parameters of the governor. Transient response processes of VSPSPS present multi-frequency characteristics with three frequencies. The low frequency is dominated by diversion pipeline and surge tank. The high frequency is dominated by pressure pipeline, pump-turbine and governor. The medium frequency is dominated by doubly-fed induction motor (DFIM) and frequency converter. Active power regulation has almost no influence on stability of VSPSPS. To suppress the influence of active power regulation on speed regulation, and realize the rapid and high-quality regulation of active power, it is suggested to select large control parameters of frequency converter. Large operating speed is beneficial to stability. Control parameters of the governor have little effect on active power regulation.
期刊介绍：
Energy Science & Engineering is a peer reviewed, open access journal dedicated to fundamental and applied research on energy and supply and use. Published as a co-operative venture of Wiley and SCI (Society of Chemical Industry), the journal offers authors a fast route to publication and the ability to share their research with the widest possible audience of scientists, professionals and other interested people across the globe. Securing an affordable and low carbon energy supply is a critical challenge of the 21st century and the solutions will require collaboration between scientists and engineers worldwide. This new journal aims to facilitate collaboration and spark innovation in energy research and development. Due to the importance of this topic to society and economic development the journal will give priority to quality research papers that are accessible to a broad readership and discuss sustainable, state-of-the art approaches to shaping the future of energy. This multidisciplinary journal will appeal to all researchers and professionals working in any area of energy in academia, industry or government, including scientists, engineers, consultants, policy-makers, government officials, economists and corporate organisations.
