摘要(Abstract):
基于我国中压配电网供电可靠性现状及供电可靠性管理实际,分析了评估模型、参数和方法中影响可靠性计算的主要问题,并给出了合理的处置办法。其中,提出的配电网模型构建思路和方法可将可靠性评估与可靠性统计评价建立起有机联系。此外,就评估指标、模型、参数、方法、流程、软件设计要求、测试算例和报告内容等系统地提出了规范性建议。其中,测试算例能考虑负荷开关、负荷变化、设施容量约束和负荷削减对可靠性指标的影响;对评估流程、评估软件和评估报告提出了明确要求;通过对可靠性指标和薄弱环节分析、改善措施及其效果等报告核心内容进行规定,确保评估报告的完整性、技术深度和实用价值。算例结果表明了所提规范建议的实用性和可操作性,可对中压配电网可靠性评估技术规范的制定起到借鉴作用。
