摘要
针对高水头、复杂管道、带上、下调压室的大型抽水蓄能电站甩负荷和泵断电过渡过程，在全面分析、处理各类复杂边界基础之上，建立了具体的基于水泵水轮机装置内特性解析理论的特征线解法。利用该法对潘家口抽水蓄能电站的校核计算表明了它的正确性和广泛的适用性。此外还对我国蒲石河和捷克的ＤＬＯＵＨＥＳＴＲＡＮＥ蓄能电站进行了可研阶段的计算分析和性能预估。
A method of characteristics based on the description of the internal characters of pump-turbines was developed to compute the transient of large pumped storage stations when unloading or power failure occurs.This method was based on all-round analysis and treatment of various kinds of complex boundary conditons, and focuses on pumped storage stations with high water head, and complex conduit system includingheadrace and tailrace surge tanks. Through its application to Panjiakou Pumped Storage Station, this methodproved to be accurate and practical. It is also used in the feasibility study of Pushihe Station in China andDlouhe Strane Station in Czech to estimate their transient characteristics.
