【摘要】：针对地区电网的特点,分析了备自投在迎峰度夏或负荷高峰时段长期退出的问题。在此基础上,提出了基于能量管理系统(EMS)开发的备自投投退策略在线分析与实时闭环控制系统。系统基于EMS获取电网实时运行信息,构建备自投通用模型。系统采用计及备自投的N-1静态安全分析快速计算方法进行一次设备的N-1故障校核,校核过程充分考虑备自投负荷均分、动作时序、潮流计算收敛状态、状态估计坏数据等影响因素,并根据预设的优先级确定备自投最优投退组合,实现了备自投投退策略的在线分析,最终利用二次设备远方控制技术完成备自投的实时闭环控制。现场应用效果表明,重载变电站备自投投入率及供电可靠性得到了大幅提升。
[Abstract]:According to the characteristics of the regional power grid, analyzes the autorestart in long-term exit Yingfengduoxia or load peak period. On this basis, put forward the energy management system (EMS) based on the development of bats control strategy of online analysis and real-time closed-loop control system. The EMS system for power grid real-time operation based on information construction the system uses the general model. And the preparation of N-1 fault self checking N-1 static security analysis for fast calculation method of a device, checking the process of considering autorestart load sharing, operation sequence, convergence state power flow calculation, state estimation and the influence factors of bad data, autorestart optimal switching combination determined according to the preset priority, realizes autorestart online switching strategy analysis, finally using two equipment remote control technology to complete the automatic real-time closed-loop control. The investment and field application results show that the heavy variable The investment rate and power supply reliability of the power station have been greatly improved.
