为了保障电力系统安全稳定运行,设计和开发了在线操作前安全校核系统。首先从工程实用性角度,分析了该系统设计目标;然后介绍了系统设计框架:包括系统模块划分和功能定位、各个模块之间的相互关系及数据交互;最后介绍了基于量化分析理论的安全校核和辅助决策并行计算技术,以及在系统实现过程中为了提高计算效率的预想故障筛选原则和网络薄弱性分析等关键技术。通过开发该系统,可以在线模拟调度操作,并获得调度操作下电网的安全稳定性及辅助决策建议。在实际电网的应用验证了系统设计的实用性和有效性。
In order to ensure the safe and stable operation of the power system, a pre-operation safety verification system has been designed and developed. First of all, from the perspective of engineering practicability, the goal of the system design is analyzed. Then, the system design framework is introduced: including the system module division and function positioning, the interrelationship among various modules and data interaction; finally, the safety school based on quantitative analysis theory Nuclear and auxiliary decision-making parallel computing technology, as well as in the process of system implementation in order to improve computational efficiency of the expected fault screening principles and network vulnerability analysis and other key technologies. Through the development of this system, the scheduling operation can be simulated online, and the security and stability of the power grid and the auxiliary decision-making suggestions can be obtained. The application in the actual power grid verifies the practicality and effectiveness of the system design.
