摘要
针对目前一次调频考核系统不能准确反映和全面评估一次调频能力的问题,在加强网源协调管理、规范和提高发电机组及其控制系统监测技术水平的要求下,开发基于广域测量系统的一次调频在线监测和考核系统,该系统以新疆电网智能调度技术支持系统为平台,在线读取广域测量系统动态数据,通过机组出力变化特征评估机组一次调频性能指标,并定义有效扰动来判断一次调频事件,监测机组实时运行状态;考虑到机组实际运行的情况,制定一次调频免考核规则。实际运行结果表明该考核系统能准确检测出机组一次调频事件,能够很好地考核机组的一次调频能力。
The current assessment system for primary frequency regulation （PFR） cannot accurately reflect and totally evaluation the ability of PFR. Based on the technology requirements of coordinating network source management, standardizing and improving the level of generator and its control system monitoring technology, this paper introduced the online monitoring and assessment system for generator unit PFR based on wide area measurement system （WAMS）. Taking the Xinjiang power grid intelligent scheduling technology support system as a platform, the WAMS dynamic data can be read on-line. According to characteristics of unit output variation, unit PFR performance indexes were evaluated, and a PFR event was determined by defining effective disturbance. Thus,the unit operation status can be monitored in real time. Considering the actual operation situation, a PFR free assessment rules was developed. Actual operation results show that the on-line monitoring and assessment system can accurately detect PFR, and can effectively assess the unit PFR ability.
