Governor control for hydraulic power plant
专利汇可以提供Governor control for hydraulic power plant专利检索，专利查询，专利分析的服务。并且PURPOSE:To provide controllably approximately constant frequency of a water wheel generator by introducing signals responsive to water level in a surge tank into a governor. CONSTITUTION:A surge tank is provided in a water channel system, and a water wheel is controllably governed by a governor. Unless water level in the surge tank is varied, water level correction signals corresponding to said water level are not generated and the frequency fa of a water generator 5 equals a set frequency fr. When the water level is varied, rises and exceeds a reference value, a water level correction unit 103 sends the correction signal to an electric system governor amplifier 102 to reduce the set frequency value, and when the water level in the surge tank descends oppositely below the reference value, said unit 103 sends the correction signal to increase the set frequency value for correcting the set frequency value of the governor. Thus, even if substantial variation of the water level occurs, the frequency fa of the generator can be controllably equalized approximately to the reference frequency.，下面是Governor control for hydraulic power plant专利的具体信息内容。
