Description

风能稳压发电方法
本发明涉及一种风能稳压发电方法。
目前，成熟的发电方法主要有火力发电、原子能发电、水利发电、风力发电等。火力发电应用最广，但能源消耗较大，且对环境的污染破坏也较大；原子能发电技术要求非常高，投资也十分庞大，目前只有少数一些国家拥有这项技术；水利发电和风力发电虽然属于洁净的发电方法，但水利发电对环境和自然的条件要求较高，其发电容量与水源是否充足，以及水的流量大小有直接的关系，而且水源均不能循环利用，因此水利发电只能在地理环境非常适宜的地方采用；风力发电是利用自然风能进行发电的方法，由于自然风的大小变化频繁，造成风力发电的电压、发电量相应变化不稳，很难给电网稳定供电。
本发明的目的是利用风能发电与抽水蓄能相结合提供一种风能稳压发电方法。
本发明的目的是由以下方式实现的：
(1)选择风力资源比较丰富的山区地形安装多台大功率风力发电机并进行联网，同时建一座变电站，将风力发电机组发出的电送入变电站；
(2)选择流域面积较大的山沟，在沟口内落差较小处筑坝建一座水库，称为下水库，在下水库最高淹没处略上游筑坝建一座水库，称为上水库，上水库的设计库容量应在下水库容量的一倍以上，在下水库的坝身上建有泄水闸门，在上水库安装有大小两台水力发电机，其容量比为2∶1，其容量之和相当于风力发电机组发电的最高峰值；
(3)在上水坝的下方设有多台用调速电机带动的大功率抽水机，其功率之和与风力发电机组最大发电量相当；
(4)变电站把风力发电机组送入的电力变成调速电机所需的电压范围给调速电机供电带动抽水机从下水库向上水库抽水，并根据风力大小来调整开启抽水机的台数；
(5)根据上水库中水位的变化来决定开启大的或小的水力发电机工作，在风力特大时，在电网用电高峰时可同时开启两台水力发电机发电。
本发明的优点是：
(1)通过调整多台抽水机的开启量，可充分把风能转化为水能；
(2)由于上水库水位变化范围很小，所以能给电网提供稳压电能；
(3)由于本方法是采用循环水发电，无需大量补充水量，充分利用了水利资源；
(4)由于山区无污染，所以能利用水库的蓄水能力给下游城镇提供优质廉价的水源。
