首先提出一种定位特高压环网开断故障下热稳问题的精准、遍历搜寻方法;然后建立了特高压直流矫正环网热稳问题的优化模型,并提出了一种快速、实用的定步长梯度下降寻优方法。求解过程中,提出了特高压环网目标线路的等效送、受端概念;同时,多直流调制灵敏度、调制方向、调制步长以及每一迭代步调制效果等的给出增强了控制策略寻优的物理意义。最后,基于实际的特高压环网工程,采用PSD-BPA仿真软件,对所提方法和策略的有效性进行了仿真验证。
Firstly,an accurate and traversal search method for locating the thermal stability problem under interruption faults of UHV(Ultra High Voltage) loop network is proposed. Then an optimization model for UHVDC(UHV Direct Current) to correct thermal stability problem of loop network is established,and a fast and practical method for fixed-step gradient descent optimization is proposed. In the solving process,the concept of equivalent sending and receiving end of the target transmission lines of UHV loop network is proposed,and the physical meaning of the control strategy optimization method is enhanced by giving the multi-DC modulation sensitivity,modulation direction,modulation step size,the modulation effect of each iteration and so on. Finally,based on the actual UHV loop network engineering,the PSD-BPA simulation software is used to simulate and verify the effectiveness of the proposed method and strategy.
