摘　　要：小水电分布式接入配电系统必然对其可靠性产生影响。建立了小水电的停运概率模型,结合负荷和其他各元件的概率模型,提出了基于时序蒙特卡罗模拟法,考虑小水电接入的配电系统可靠性评估方法。以此方法对接有小水电的IEEE RBTS改进系统进行了可靠性评估,验证了该方法的有效性。并且通过与原系统可靠性指标的比较,分析了小水电的接入对配电网可靠性指标的影响及这种影响的特点,分析结果对小水电的设计工作者在SHP的建设选址方面能起到一定的参考作用。With the small hydro power considered, the reliability of the distribution system will be effected consequently. The probability model of small hydro power is established firstly. Combined with other elements model, based on sequential Monte-Carlo simulation, a reliability evaluation method for distribution system with small hydro power is proposed. Applying this method, reliability indices of the IEEE RBTS distribution system including small hydro power is calculated. It is proved that the proposed method is effective. Besides, the effect and its characteristic for evaluation indices of distribution network are analyzed. The analyzed results can supply some references for designer that designs small hydro power in its location election.
