摘　　要：以提升高比例新能源送端电网的暂态电压安全性为目标,研究调相机组的选址和定容优化配置问题。基于新能源机组高/低电压安全穿越标准建立暂态电压安全评估指标,提出调相机安装站点优选方法。综合考虑送端电网暂态电压安全和外送通道功率输送要求,构建调相机配置容量优化模型,提出应用天牛群算法的模型求解方法。通过对高比例新能源送端电网仿真分析,验证了所提调相机优化配置策略能够有效提升送端电网暂态电压安全水平并减少故障扰动下外送通道功率与故障前调度值偏差。Aiming at improving the transient voltage security of the high-proportion renewable energy sending-end power grid,an optimal configuration method of synchronous condenser was studied.According to the high/low voltage safety ride-through standard of new energy units,a voltage safety evaluation index was established.The candidate installation sites of condenser were chosen optimally.Considering the requirements of transient voltage safety and power transmission of outgoing channels in the sending-end power grid,the capacity optimization model of condenser was constructed,and a solving method for the optimization model using particle swarm algorithm was proposed.By the simulation results in a high-proportion new energy sending-end power system,it was verified that the proposed optimal configuration of condenser could effectively improve the transient voltage security level and reduce the deviation of the transmitted power of the outgoing channel.
