摘要(Abstract):

介绍了逆变站的模型及其控制方式,分析特高压直流受端系统静态电压稳定过程中,站内换流变分接头调节范围对换流器消耗无功功率的影响,以及站内无功补偿对受端系统静态电压稳定能力的影响。结合2016年华东电网规划数据,通过PSS/E仿真计算,分析了宁绍特高压直流输电对绍兴换流站交流母线静态电压稳定的影响,并验证了建立逆变站详细模型对电压稳定分析的重要性。
The paper introduces the model and control mode of an inverter station and analyzes the impact of converter transformer tap adjusting range on the reactive power of converter during static transmission voltage stabilization of UHVDC power receiver system, as well as the impact of reactive power compensation on the static voltage stabilization capability of power receiver system. Based on the planning data of East China power grid in 2016, the impact of Ningbo-shaoxing UHVDC transmission system on the static AC bus voltage stabilization of Shaoxing converter station is analyzed by PSSE simulation; besides, the importance of building a detailed inverter station model to voltage stabilization analysis is verified.
