中文摘要:

在考虑投资成本具有限定性的前提下，提出了一种电压暂降和谐波谐振监测点的统一优化配置方法。定义并量化了电压暂降可观性指标和谐波谐振可观性指标；综合考虑了电压暂降与谐波谐振可观性以及投资成本经济性，基于层次分析法和模糊综合评价法给出了监测点配置方案综合性能的量化分析方法；提出了以配置方案综合得分最高为目标，以监测装置数不超过限值为约束的监测点统一优化配置模型，并基于离散粒子群优化算法进行求解；基于IEEE-30节点测试系统进行了暂降与谐振监测点统一优化配置，仿真结果表明所提方法可在确保配置方案所需监测装置数满足投资成本限定的条件下，获得电压暂降可观性、谐波谐振可观性与监测装置数目经济性三者协调最优的监测点配置方案。

英文摘要:

Considering the limitation of investment cost, a unified optimal configuration method of voltage sag and harmonic resonance monitoring points is proposed in this paper. The observability indices of voltage sag and harmonic resonance are defined and quantified; Considering the observability of voltage sag and harmonic resonance as well as the cost economy of investment, the quantitative analysis method of the comprehensive performance of monitoring point configuration scheme is given based on analytic hierarchy process (AHP) method and fuzzy comprehensive evaluation method; Then, a unified optimal configuration model of monitoring points is proposed, which takes the highest comprehensive score of the configuration scheme as the objective and the number of monitoring devices not exceeding the limit as the constraint, which is solved based on the discrete particle swarm optimization algorithm; Finally, the unified optimal configuration of sag and resonance monitoring points is carried out based on IEEE-30 bus test system. The simulation results show that the proposed method can obtain the optimal configuration scheme of monitoring points, whose voltage sag observability, harmonic resonance observability and economy of monitoring devices are coordinated optimal under the condition that the number of monitoring devices meets the investment cost limit.
