| 摘要: |
| 提出一种基于并行模式的多预想故障静态电压稳定辅助决策方法用于提高系统静态电压稳定性。根据灵敏度与经济成本计算控制措施性能代价比指标并实施分群控制。根据电压模态分析结果进行无功功率调整，不达控制目标时再计算有功综合灵敏度补充有功功率调整。若多预想故障的综合控制措施引起正常运行方式母线电压越上限，则求解无功综合灵敏度后调整无功。基于并行平台形成包含故障信息、控制对象、控制总量及分配方式的多个控制方案，并根据迭代结果快速缩小搜索空间。通过对浙江电网某实时断面的仿真分析，验证了所述方法的有效性和实用性。 |

| Abstract: |
| A method of auxiliary decision-making based on the multi-contingency in parallel mode is proposed to improve the system static voltage stability. The performance - cost ratio is calculated according to the sensitivity and economic cost of control measures for group control. The reactive power is first adjusted according to the results of voltage mode analysis. If the control target is not achieved，the active power adjustment is then supplemented according to the calculated active power comprehensive sensitivity. If the comprehensive control measures may cause bus overvoltage in normal operating mode，the reactive power is then readjusted according to the calculated reactive power comprehensive sensitivity. Based on the parallel computation platforms，different control schemes containing the contingency，control object，total adjustment and allocation mode are formed and the search spaces are quickly reduced by iteration. The efficiency of the proposed method is tested by the simulation for a real -time section of Zhejiang Power Grid. |
