摘要
针对电网谐波的影响,介绍了一种抽水蓄能发电站变频启动方式。对该启动方式中必不可少的装置—变压器的漏抗对电网谐波电压以及谐波电流的影响进行了分析,利用仿真软件Saber对浙江桐柏抽水蓄能发电站静止变频器整流部分为六脉相控整流的实例进行了仿真建模,并针对该方案提出了一些建议以减小电网谐波。研究结果表明,该方法具有广阔的推广应用前景。
Aming at the iufluence of power harmonic, a static frequency converter （SFC） was proposed to start a pumped storage power station. The harmonic effect by transformer leakage inductance indispensable in grid was analyzed. The simulation of the Tongbo pumped storage power station with six pulse phase control rectifier in the static frequency converter of Zhejiang Province as an example was made by Saber. Suggestions were proposed to suppress the harmonic generated by SFC. The experimental results show that the method illustrates a good prospect of application and extension.
