Operation controller of hydroelectric or pumping-up power plant
专利汇可以提供Operation controller of hydroelectric or pumping-up power plant专利检索，专利查询，专利分析的服务。并且PURPOSE:To average the consumption of lifetime for each electric generator or generating motor, by obtaining the coefficient of lifetime consumption based on the frequency of operations and the time of operation. CONSTITUTION:The start-stop signal of each of machinery 21-2n is supplied to an operation controller 3 via a signal line 5 to store the time of operation and the frequency of operations for each machinery. The controller 3 decides the machinery to be started or stopped based on the stored time of operation and the frequency of operations plus the inhibition state of operation of each device which is supplied from an ooeration control board 1. The number of the machine to which the start of stop is decided in such way is displayed on the board 1 via a signal line 6. Thus an operator gives a control to the corresponding device through the board 1 and based on the machine number displayed on the board 1.，下面是Operation controller of hydroelectric or pumping-up power plant专利的具体信息内容。
