Abstract

PURPOSE: To control the increase in the rotational frequency of a turbine generator, by adding to the load sensing unit of a reheat steam turbine a high-speed valve controller which quickly opens an intercept valve when an electric output falls and the electrical current of the generator increases.
CONSTITUTION: When a trouble happens in a line, the output Pe of an electricity generator decreases and its electrical current I increases. At that time, an intercept vlave is quickly closed by the judgement circuits 8, 9 of a high-speed valve conroller. When a load is disconnected, the generator output Pe and the generator current I become zero. At that time, a regulating valve and the intercept valve are both quickly and entirely closed in accordance with the establishement of a condition through AND circuts 5, 6, 7 if reheated steam pressure pH is not lower than a set value KL2. The rise in the rotational frequency of the turbine generator can thus be suppressed at the time of the disconnection of the load or the occurrence of the trouble in the line.
