新一代能量管理系统的设计与发展

摘要

随着电力系统的发展引入新的动态问题,能量管理系统(EMS)原始设计已经无法满足电力系统监测、保护及控制的要求.EMS的新设计需求包括现场数据集成,基于对数据分析的知识提取引入新的决策工具及传统设计到新设计的灵活转变.首先指出了原始EMS的设计局限,并介绍了EMS功能框架特点.从告警处理、故障分析和状态估计三个方面改进现有EMS设计,主要体现在智能告警处理器、自动故障定位及网络拓扑分析仪等应用的改进.最后引入了四个EMS新功能,增加的新功能主要与新数据分析相关,如连锁故障的检测和恢复,匹配数据和模型及自动故障分析等.%As development of the power system and introducing new dynamic behavior,the existing EMS design is not able to respond to the need to monitor,protect and control power system.The desirable features include integration of field data,introduction of new decision-making tools based on data analytics for knowledge extraction,and flexible transition from legacy to new design.Firstly,the limitations of the original EMS design and EMS functional framework were introduced.Then,the existing design was enhanced for three functions including alarm processing,fault analysis and state estimation.The three functions have been identified to demonstrate improved performance of the mentioned applications:intelligent alarm processing,automated fault locating,network-topology processing.Finally,four exemplary new EMS functions were introduced.New functions are primarily related to new data analysis such as detection and mitigation of cascade fault,matching data and models and automatic fault analysis.
