专利汇可以提供Water turbine control means专利检索，专利查询，专利分析的服务。并且In a control means of a water turbine generator, it has been known that the inertia effect of water in a water conduit for directing water to the turbine has an adverse effect on the controllability of the water turbine. In this view, said control means is combined with means for imitating the inertia effect to compensate the inertia of the water in the conduit, so that the controllability of the water turbine is improved.，下面是Water turbine control means专利的具体信息内容。

权利要求

1. A water turbine control system comprising a water turbine, a water conduit for introducing water into the water turbine, water flow adjusting means for adjusting the water flow introduced into the water turbine, means for adjusting said water flow adjusting means in accordance with load so that the speed of the water turbine is maintained substantially constant, means for simulating the inertia effect of the water in the water conduit which is a cause of instability of the water turbine control system by operating in reverse direction to a desired operation upon operation of said water flow adjusting means, and means for compensating the inertia effect of the water in the water conduit by said simulating means.

2. A water turbine control system in accordance with claim 1 which further comprises a governor which is combined with means having differentiating characteristics so that the output signal of said means for simulating the inertia effect of the water in the water conduit, which means is provided as a compensating means for the governor, is fed back only transiently during turbine load fluctuation into the input signal of the governor.

3. A water turbine control system in accordance with claim 1 in which a signal corresponding to the opening of said water flow adjusting means of the water turbine is used as the input signal of the means for simulating the water conduit which is the cause of instability of the water turbine control system, the output signal of said simulating means being fed back as one of the input signals of the governor.
