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:
      In view of the characteristics of the regional power grid, an analysis is made of the problem of long-term quit busbar automatic transfer switches(BATS)in the summer peaks or peak load periods. On this basis, a BATS strategy in real-time online analysis and closed-loop control system based on energy management system(EMS)system is developed. The system gest real-time operational information of the grid from EMS, creates the common model of BATS. The system uses a fast computing method of N-1 fault check in static safety analysis considering BATS, The Checking process takes into full account standby load sharing, action sequence, flow calculation convergence state, state estimation of bad data and other factors. and determines the optimal BATS combination according to a preset priority. After realizing the BATS strategy in real-time online analysis, the BATS closed-loop control using a secondary device remote control techique is achieved. Field application effect shows that the input rate of BATS and power supply reliability in reload transformer substation is dramatically increased.
