Abstract

本发明涉及一种蓄能调峰水电站，包括上水库、水轮发电机组和下水库，其特征是上水库为年调节水库，下水库为日调节水库。本发明比抽水蓄能调峰水电站减少大约30％的电能损失。

Description

一种蓄能调峰水电站
技术领域
本发明涉及电网调峰领域，特别是涉及一种蓄能调峰水电站。
背景技术
用电有高、低峰之分，高峰时电力负荷超过发电能力，低峰时电力用不完，白白浪费。现在通常采用抽水蓄能水电站把低峰时多余的电力用可逆式泵水发电两用机组来抽水，把下水库的水抽到上水库，用电高峰时再放水发电来调节用电峰期。但是，电力从发电厂输送到抽水蓄能水电站约损失10％，抽水和放水发电损失25％，总共白白损失了大约32％的电能。如果把一条河流一天的总水量在短时间内用来发电以调节电网峰期，这样可以避免输送电力、抽水和放水所造成的损失，但是这样做会造成水库下游的河道交替地刮大水和断流，影响船只通航和鱼类生长等等。
发明内容
本发明的目的是提供一种蓄能调峰水电站，不但可以节约大量的电能，而且可以保证水库下游河道的流量稳定，以保护通航和渔业。
按此目的设计的一种蓄能调峰水电站，包括上水库、水轮发电机组和下水库，其特征是上水库为年调节水库，下水库为日调节水库。
所述的上水库的库容至少能够对水量进行年调节。所述的下水库的库容对水量至少能够进行日调节，并在下水库的堤坝旁边设置着能调节一天水流流量均衡的水闸或水轮发电机组。
本发明不但比现有的抽水蓄能调峰水电站造价低，选址容易，而且能保持水库下游河道的水流量的均匀和减少大约30％的电能损失。
附图说明
图1是本发明一个实施例示意图。
具体实施方式
下面结合附图及实施例对本发明作进一步详细描述。
参见图1，一种蓄能调峰水电站，包括上水库1、水轮发电机组2和下水库3，其特征是上水库为年调节水库，其库容至少能够调蓄一年的水量；下水库为日调节水库，其库容对水量至少能够进行日调节，并在下水库的堤坝旁边设置着能调节一天水流流量均衡的水闸或水轮发电机组4，把上水库一天发电量的水量均衡地排泄到下游河道5，以防止下游的河道交替地刮大水和断流。
所述的上水库1一般是一条河流的源头水库，库容量较大，具备年调节或多年调节的能力，当然，如果上水库不是源头水库，比如在上水库的上游有一个年调节水库，这样，上水库的库容就无需太大了；所述的下水库3的水轮发电机组除了可以调节下游流量的均匀外，还可以发电，以增加水能的利用率。
用电高峰期一般每日只有2小时左右，当电网处于用电高峰时，上水库把一天的发电量的水通过发电厂房内的水轮发电机组在大约2小时左右全部发出，以消除电网负荷，发电后的水暂时储存在下水库里，再由下水库的水闸或水轮发电机组均匀地分配下游河道一天的流量，以防止下游的河道交替地刮大水和断流。
由于把一天的发电量压缩在大约2小时左右，因此，一座通常只能发电20～30万KW的水力发电站可以改造成百万千瓦级的调峰电站，效益非常显著。如果把中国福建省尤溪县的30万KW街面水电站改造成蓄能调峰水电站，装机容量可达180万KW。
