d一onll xjtongd一onJ一Pingher飞g电力系统电力平衡(power ba一anee of eleetriepower system)电力系统中电源与负荷的平衡。根据预测的电力系统负荷来确定电力系统的发电容量。它是电源发展规划的组成部分。电力平衡的内容是:①工作容量计算;②备用容量计算;③水电平衡;④火电平衡。计算结果可用电力平衡表或电力平衡图表示。在编制电力平衡表的过程中,常常要做多个方案,反复平衡,才能得到预期的结果。 工作容t计算水电厂、火电厂工作容量分别计算。根据规划期内预测投产的水电厂的保证出力、强迫出力、预想出力及电力系统负荷曲线计算水电工作容量。系统负荷减去水电工作容量即为火电(包括核电)工作容量。(见电力系统工作容童) 备用容t计算用系数法或电力不足概率(LO-LP)计算出备用容量并在水、火电厂之间合理分配.求出水电备用容量及火电备用容量。(见电力系统备用容黄) 备用容量与工作容量之和是保证系统安全可靠和不间断供电所必需的容量,称之为必需容量。 水电平衡水电装机容量与必需容量之平衡。由于水电厂在某些情况下运行水头低于设计水头或其他原因,水电厂的最大出力(亦称预想出力)有时低于装机容量,装机容量与预想出力之差称为受阻容量。在进行水电平衡时,预想出力必须大于水电必需容量,两者之差称为空闲容量。在平衡时可能遇到如下两种情况:①空闲容量过大,此时需研究提高水电必需容量的可能性,如扩大联网或复核水电装机容量.研究减少水电装机容量的合理性;②空闲容量为负值.即必需容量大于预想出力,则应研究降低水电工作容量及备用容量的合理性,或研究扩大水电装机容量问题。 火电平衡火电装机容量与必需容量的平衡。在平衡时,火电受阻容量及退役容量应予以扣除。通过平衡,可以确定火电新增装机容量投产的进度。平衡结果应使火电保持盈余。但由于投资或其他原因的限制,无法增加足够的容量使火电保持平衡时,系统将发生缺电现象。
