基于多Agent的电压暂降实时分析系统的研究

暂降电能质量问题分析对时效性要求越来越高,但是目前暂降问题分析的系统多为离线评估方式,此系统的时效性较差。同时暂降事件在电网中具有一定的传播特性,事件发生后将会有多个监测点捕捉到事件发生,为了提高时效性需要对多个监测点监测到的数据同时计算分析。电压暂降分析所具备的分布式、实时性的特征与多Agent系统具有高度的一致性。论述了一种基于多Agent技术,采用JADE开发平台,对多个同时捕捉到的电压暂降事件进行实时、并行计算处理的方法。该方法将后台集中计算方式的离线分析处理前移,实现实时的在线分析处理。该方法使得电压暂降分析的实效性更强,为及时发现问题、处理问题赢得时间,避免造成更大损失。

Research on real-time analysis system of voltage sags based on multi-agent

Voltage sag in power quality requires better timeliness. While most of the voltage sag analysis systems are based on off line mode, they all have a bad timeliness. Also voltage sag has propagation property in the power grid. Many monitoring sites will capture the voltage sag event, so in order to get better voltage sag timeliness, all data should be computed in different monitoring sites as soon as they are gathered. This distributed and real time analysis approach shares many similarities with multi-agent system. This paper proposes a JADE-based multi-agent technology to compute voltage sag events in distributed mode in real time. This technology has better timeliness because the analysis is proceeded earlier than the old centralized off-line analysis, which will help trace and resolve the abnormity in time and will definitely reduce the loss due to the abnormity.
