发电厂输出的电如果没有用掉，那些电到那里去了？

忘记了。转化成热能再发电

现在都是电网连在一起，几个区域网连城一个大网络，多发的电会输送到其他的缺电的地方，如果发现过发的情况都会由电力调度要求部分发电厂的部分机组停运的，没有像你说的用不掉，要不就是发给缺电的地方，要不就 ...

该休息了，明天还有课啊

假设现在全国都不缺电，突然几个用电大户停止用电，那发电机组能在瞬间停止运转，那反应时间内发出的电又会跑到什么地方去？*.*lll

要是能自动控制就好了
线路上有侦测仪器
自动调整发电机的动作
我想国内还没这么先进吧

呵呵,
减少发电量,只能如此,要不就用掉
飞车很威险的

发电机本身也是一个电动机来的

这时候 用电大户停止用电－电网频率上升，因为电能是不能储存（现阶段）故多余的电将导致电厂电机失步飞车 就是在大电网拖着发电机越转越快 最终电网将崩溃
单纯发电机停止的话 电网频率下降 最终也会崩溃

那我们的夜晚电费半价怎么解释，难道电厂主动亏损

嗯，专业<br />
<br />
其实发电和用电可以用骑自行车来比喻<br />
正常匀速前进的时候骑车人用力均匀<br />
要是突然车链子断了（类比用电户突然断电）<br />
骑车人会有啥感觉呢<br />
负载没了<br />
当然脚踩空了（类比发电厂飞车事故）<br />
这时 ...
