油田配电网的可靠性与灵敏度分析

Oilfield Distribution Grid Reliability and Sensitivity Analysis

针对油田配电网的特点,采用网络等值与最小路相结合的方法对其进行可靠性评估。提出采用灵敏度分析的方法寻找系统的薄弱环节。首先利用网络等值法对配电系统进行化简,然后利用最小路法求出各负荷点的可靠性指标,最后计算可靠性指标对元件的灵敏度大小并排序。利用Visual C++6.0实现配电网可靠性评估的程序设计。结合华北油田某配电网的具体实例进行可靠性评估并进行灵敏度分析,以验证算法和程序的正确性。

This article describes the characteristics of the power system field, through the network equivalent with minimal path method for oilfield distribution grid reliability evaluation. First, power distribution system is simpli- fied using the network equivalent, then the load point reliability indices are calculated using the minimal path meth- od. Finally, the sensitivity of reliability index to different the components is calculated and sorted. The distribution system reliability assessment program is designed by using Visual C ＋ ＋ 6.0. The reliability assessment and sensi- tivity analysis are conducted by a specific example in Huabei Oilfield distribution network, and the results verify the correctness of the proposed algorithms and programs.
