基于ASP.Net的电网事故处理辅助决策系统

Accident-handling decision-making system for power grid based on ASP.Net

为解决电力调度员在使用传统的离线分析决策方法处理事故时"整体速度偏慢、过程用时较长且处理方案不够完善"等问题,将ASP.Net技术应用到开发电网事故处理辅助决策系统中。开展了各类电力设备故障时处理方法的分析,以优化的处理方案为基础,利用数据库与网络拓扑原理,建立了事故分析及处理在线辅助决策系统,明确了事故处理时变电站与调度室之间的关系,规范了事故信息报送格式,具有较高的可维护性、可扩展性和安全性。结果表明,辅助系统给电力调度员提供了良好的技术支持,事故决策方案更成熟准确,整个事故处理恢复送电过程所需时间明显缩短,比较系统使用前后情况,发现平均事故处理时间缩短了15%,具有较高的应用价值。目前,该方案已在宁波电网内各变电站及地调系统中投入使用。

Due to the expanding of the power grid, the traditional off-line analysis decision-making method can hardly meet the special requirements of the modern power grid. Aiming at solving the problems existing in dispatching, an accident handling assistant decision-making system was proposed. The system provides various typical reference scheme for accident treatment. Based on the optimized treatment, the on-line decision-making system has been established using the database and the topology of the network principle. It clears the relationship between transformer substation and dispatching department, and makes the accident submitted information format standarded. Furthermore, compared with the traditional method, it has better convenience, maintainability, expansibility and security. The results indicate that it has greatly shortened the response time of the accident by up to 15%, and made the decision more mature and accurate. The system has been applied to Ningbo electric power dispatching system successfully.
