摘要:

从城市高压电网的实际特点出发,采用降阶枚举法进行城市高压电网最优运行网架的在线确定计算.开关的状态用整型变量表达,所有开关状态的组合构成了电网可能运行方式的全枚举集;考虑继电保护等各种实际电网运行约束后,大幅度减少了可能的运行方式数;对有限数目运行方式的准确计算,保证了结果的最优性和计算的快速性.该思路已分别用于"城市电网智能决策支持系统"中电网事故后恢复方案、当前运行方式以及将来任一时刻的最优网架运行方案的确定.在南阳城市电网的实际试运行表明了该方法的有效性和实用性.

Abstract:

Starting from the actual characteristics of urban high-voltage power grid, the reduced-order enumeration method is used to determine the online operation grid of urban high-voltage power grid. The state of the switch is expressed as an integer variable, and the combination of all switching states constitutes a complete enumeration of the possible operation modes of the grid; After considering various practical grid operation constraints such as relay protection, the number of possible operation modes is greatly reduced; The accurate calculation of a limited number of operation modes ensures the optimality of the results and the rapidity of the calculation. This idea has been used to determine the post-accident recovery scheme, the current operation mode and the optimal grid operation scheme at any time in the future in the "intelligent decision support system of urban power grid". The actual trial operation of Nanyang urban power grid shows the effectiveness and practicality of the proposed method.
