摘　　要：无功电压波动会影响到特高压电网运行稳定性和安全性,但现行无功电压控制优化方法在实际中优化效果并不理想,不仅电网有功损耗比较高,而且电压越限也比较大,为此提出特高压电网无功电压控制优化方法研究。以电网无功交换最小、有功损耗最小为目标建立多目标函数,设定约束性条件,建立无功电网控制模型,利用粒子群算法对模型优化,实现特高压电网无功电压控制优化。经实验证明,设计方法应用下电网有功损耗和电压越限得到了有效的降低,优化效果良好。Reactive voltage fluctuation will affect the operational stability and safety of UHV power grid,but the optimization effect of the current reactive voltage control optimization method is not ideal in practice,not only the active power loss of the power grid is relatively high,but also the voltage exceeds the limit is relatively large.Therefore,the optimization method of reactive voltage control of UHV power grid is proposed.With minimum reactive power exchange and minimum active power loss as objectives,multiple objective functions were established,binding conditions were set,and the reactive power network control model was established.Particle swarm optimization was used to optimize the model,and the reactive power and voltage control optimization of UHV network was realized.The experimental results show that the active power loss and voltage overstep can be effectively reduced under the application of the design method,and the optimization effect is good.
