基于故障模式后果分析法的配网网架结构可靠性研究

Study on distribution network structure reliability based on failure mode and effect analysis method

针对济宁太白湖区配电网供电能力有限、电网结构简单及配网管理薄弱等问题,对当前负荷利用自然增长法进行了预测,并详细论述了网架结构设计重要因素与可靠性,提出了基于故障模式后果分析法的太白湖区目标网架结构,并给出了现状网架向目标网架的过渡方案。通过分析所提方案实施后的效果,验证了开闭所供电模式下的目标网架结构具有较高的供电可靠性。

As to problems such as limited power supply ability of distribution network, simple power grid structure and weak distribution network management in Taibai lake region, Jining, the current load is forecasted by using natural growth method and important factors and reliability in designing network structure are elaborated in detail. On the basis of all above, the objective network structure is proposed based on failure mode and effect analysis method and the scheme of make the transition from current to objective network structure is given. The effect after the implementation of the proposed scheme through analysis verifies that the objective network structure has more reliability in power supply under the mode of power opening or closing .
