摘要
考虑到能效电厂的运行具有随机性,能效电厂出力不能简单地用常规设备与节能设备的容量差来计算,而应通过监测能效电厂的运行情况得到能效电厂的出力曲线。文中采用解析法来计算发电系统可靠性,将监测到的能效电厂的出力曲线从负荷曲线中分离,将分离后的净负荷曲线与常规电厂的停运概率表相结合计算发电系统的可靠性指标,同时,利用电力不足期望值与年最大负荷的关系计算能效电厂在发电系统中的有效容量,并通过算例说明了该思路的实现方式。
As the operation of efficiency power plant（EPP） is random,therefore,the output of EPP cannot be calculated simply with the capacity difference between conventional equipment and energy-saving equipment.Rather,the output curve of an EPP is obtained by monitoring its operation.The analytical method is used to calculate the reliability of power systems.First the output curve monitored by the EPP is separated from the load curve.Then the power system reliability indices are calculated by the net load curve after the separation and outage table of the conventional power plant.Meanwhile,by use of the relationship between loss of load expectation and annual peak load,the effective capacity of EPP in the power generation system is calculated.The way the above-mentioned idea is illustrated with an example.
