电力系统调峰
peak load following of electric power system
d一onl一x}tongt一oofeng电力系统调峰(peak load following of eleetriepowersystem)为满足电力系统日尖峰负荷铸要，对发电机组出力所进行的调整。 尖峰负荷是由于一日24小时内用电需求不均匀而形成的。一般一昼夜之内，在上午和照明时间，出现两次尖峰负荷，深夜则为用电最少的低谷负荷(仅为尖峰负荷的5。%~70%)时间。尖峰负荷持续时间相对较短。 尖峰负荷与低谷负荷的差值很大，因此要求有些发电机组在低谷负荷时停机，而在尖峰负荷到来之前迅速起动并增长出力，尖峰过后即降低出力和停机(见图)。这些机组称为尖峰负荷机组或调峰机组。它们具有起动时间短、出力变化快和可以频繁起停的性能。 必须在电力系统发展规划中列入调峰措施，决定选用机组类别，根据系统运行需要对其建成进度妥善安排。具体措施有:①采用水电机组调峰。②采用抽水抽水留能机组所发电力黔乡茱 的次。租峨喇钧份一舰尖峰负祠机组所发电力抽水公能御幽拍水中间负蔺机组所发电力，一一一一一一一一一一、、、___，羞本负蔺机组所发电力12 16幼24 时序，时 调峰示意图蓄能机组调峰，低谷负荷时抽水，尖峰负荷时发电。此措施具有显著的调峰效益。③采用专门调峰的火电机组。①对已装常规火电机组进行改进，使之降低最低允许出力或能每日开停而实行两班制运行等，以减轻尖峰负荷和低谷负荷差值大所引起的调峰困难。
