摘要/Abstract

摘要： 研究了变电站无人值守相关问题下，发电机的并行恢复策略。先针对现阶段电网运行状况建立了变电站无人值守情况下线路的启动时限模型，得到了线路启动的时间成本期望。再建立了发电机有功出力和进相运行能力关于时间的函数。然后定义了电源中心的概念，并以之为依据求取了机组启动的距离成本。考虑机组启动的多种限制因素，调用迪克拉斯算法，计算考虑时间成本和距离成本的机组最优启动序列，通过并行校验确定机组启动顺序。最后应用IEEE39节点算例对所提出方法进行了分析验证，结果表明可明显提高机组恢复效率。

Abstract: The generator parallel recovery strategy is studied in the paper based on the related problems of unattended substations. Firstly, in view of the existing operation condition of power grid, a line startup time model is established for unattended substations to obtain the line startup time cost expectations. Then, a time-depended function is established for the generator active power output and the leading phase capability. After that the concept power center is defined in the paper, based on which the distance cost of generator startup is calculated. With consideration of a variety of constraints of the generator unit startup, the Dijkstra algorithm is used to calculate the optimal generator unit startup sequences of time and distance cost, and determine the generator unit startup sequence through parallel calibration. At last, the proposed method is validated on the IEEE 39-bus power system, and the result shows that it can obviously improve the efficiency of generators restoration.

Key words: black startup, Dijkstra algorithm, start-up time, parallel recovery, unattended substation
