| 摘要: |
| 备自投对保障电力系统供电可靠性非常重要，站内备自投孤立运行，缺乏电网全局信息，不利于充分发挥备用电源投入功能。提出基于集中校核与分散控制的备自投系统，该系统包括监视分析、在线投退和离线校核3个方面的功能。同时介绍了与备自投系统技术实施相关的若干关键技术，包括备自投模型、基于风险评估的备自投投退策略、数据可靠性校核和网络备自投控制校核。应用实例表明，备自投系统可以综合全网信息，降低电网运行风险。 |

| Abstract: |
| Automatic switchover device is very important to ensure the reliability of the power system. However, the equipment is deployed in substation construction and lack of global information grid, which is not conducive to give full play to the standby power input function. This paper proposes to establish the centralized checking and decentralized control automatic switchover system. The system includes three functions, i.e. monitoring and analysis, online switching, offline check. At the same time, this paper introduces several key technologies related to the system, including the modeling of automatic switchover, control strategy based on risk assessment, data reliability and control check of power network automatic switchover system. Application examples show that the centralized checking and decentralized control automatic switchover system can integrate the whole network information and reduce the risk of power grid operation. |
