A New Application from ABB in CSCS for large Pumped Storage Power Station in China

摘要

The Yixing Pumped Storage Project objective is to increase the overall efficiency of the power sector in Jiangsu Province. It eases acute peaking problems and improves the generation mix that will create the conditions for more flexible dispatch and improved supply reliability, an essential requirement for well wellfunctioning competitive markets. The project components are: 1) -functioning construction of the Yinxing pumped storage power plant, a new upper reservoir, new main dam and subsidiary dam, and the underground powerhouse? 2) assistance to the restructuring of the power sector? and 3) construction of a double circuit transmission line to connect the Yixing pumped storage plant to the East China 500 KV network. The project will contribute to energy sector transition from a fully state stateowned monopolistic sector to a diversely owned, market owned oriented sector in which are promoted clean fuels, renewable energy, energy efficiency and assistance to poor western areas to develop their energy resources for local growth and export to other regions. The basic cycle of operation consist of generating during peak load periods and pumping during off – peak periods. The pl plant can also run in condenser mode to stabilize the grid ant voltage. The Yixing pumped storage power plant consist of four sets of vertical shaft, single singlestage, -stage, Francis, reversible Units, each with a capacity of 250MW. (total plant capacity of 1000MW). ABB as a subcontractor to GE on the project is providing CSCS (computer supervisory control system) and auxiliary electrical systems. ABB will deliver control, protection and excitation systems, static frequency converters, generator circuit breakers, station se service systems and rvice cabling. The project is implemented jointly by ABB Canada and ABB Norway with active support from ABB China. The Paper he will introduce the solution of CSCS from ABB for Yixing Pumped Storage Power Station.
