摘　　要：为满足大电网在线分析和控制要求,提出了一种基于计算集群并行的静态电压稳定预防控制计算方法。基于P-V曲线计算分岔点附近的电压模态分析结果筛选无功功率控制措施。基于电压薄弱区节点有功-电压灵敏度信息,补充有功功率调整措施。以控制代价最小为目标,基于分布式并行计算平台,形成多种控制方案。采用P-V曲线计算与控制方案枚举相结合的并行计算模式提高收敛速度。通过对华东电网某实时运行断面的仿真分析,验证了所述方法的有效性和实用性。To satisfy the requirement of online analysis and control for power grid, a parallel calculation method for the prevention control of static voltage stability is proposed. The reactive power control measures are screened out based on the results of voltage modal analysis near the bifurcation point of P- V curve, while the active power adjustment measures can be supplemented according to the sensitivity information of the active power-voltage at different nodes in the weak voltage area. With the minimum control cost as the optimization objective, various control schemes are formed based on the distributed parallel calculation platform. The convergence rate is improved by adopting the parallel calculation of P-V curves together with the control schemes. The effectiveness and practicality of the proposed method are verified through the simulation on one real-time operation section of East China power grid.
