Abstract
PURPOSE: To reduce the rpm of a steam turbine in a short time period by applying a load to the turbine through shorting output terminals of a generator and supplying an excitation current to a rotor and then remove the necessity of vacuum break in a steam condenser.
CONSTITUTION: A short-circuit of output terminals 40 of a generator 30, directly connected to turbines 2 and 3, and an application of an excitation current to a rotor as a load permits rotation energy to be converted to an electric current which flows through a closed circuit of a stator and causes the current to be consumed as a heat energy. This serves to apply a break force onto the turbines 2 and 3, reducing their revolution speeds in a short time period. The above-stated procedure can reduce promptly the rotation speed of a turbine, which is rotating at an rpm in a dangerous rotation speed range, without causing any vacuum breaking in a steam condensor, thereby solving the discharge problem of radio active substances from the steam condenser resulted from a mechanical vacuum pump operation and reducing the discharge rate of radioactive substances from a stack.
