摘要
状态估计软件运行维护是电网调度自动化专业的一项基础工作,国家电网调度中心对各省调状态估计合格率提出了明确要求。本文介绍了在冀北D5000系统上采用的状态估计调试与日常运行维护方法,从电网模型、参数和量测数据等方面提出了维护时的注意事项。在冀北电网的实践证明,本文的调试方法是行之有效的。
The state estimation software maintenance is a basic work for power grid dispatching automation, so state estimation qualified rate was put forward by State Grid Corporation Dispatching Center to make clear a requirement on the provincial dispatching center. The DS000 system in Jibei on the state estimation method of maintenance debugging and routine operation was introduced in this paper. And maintenance of attention from the grid model, parameters and measurement data etc. were given. Practice in Jibei Grid proved that this debugging method was effective.
