摘要
介绍了惠州抽水蓄能电站机组球阀和导叶的关闭规律,在机组甩负荷试验过程中分析并排除测压管路音频共振的影响,以确保真实反映机组的实际压力脉动情况;实测试验证明,单机甩负荷实测与仿真计算结果吻合较好,为双机甩负荷、四机甩负荷等试验的安全进行提供了技术支持。
The paper introduces closing law of global valve and guide vane of Huizhou pumped storage power plant,and it analyzes and gets rid of impact of acoustic resonance in piezometric tube in the process of load shedding test in order to reflect actual pressure fluctuation of units.The test show that the load shedding test of unit can well accord with simulation calculation,providing scientific basis for safe operation of dual-unit and quarter-unit load shedding.
