Abstract

PURPOSE: To continue a speed load control while the generator is cut off the load or in the isolated operation, by maintaining the turbine speed at a constant level with steam from the turbine bypass valve released.
CONSTITUTION: A low value preference circuit 6 passes low value signals along in preference with comparison between output signals from the speed load control circuit and the pressure control circuit. The signal thus passed opens or closes a steam adjusting valve. An adder 8 subtracts a signal K and then, a signal generated from a bias setting device 9 from a signal F. Thus, it provides a signal N to a reactor controller through a limiter 10. When a second bias setting device 11 shows a large absolute value, the adder 8 is given a signal oppostie in code so that the amount of steam passing the valve reaches 10 α% of the total flowrate. If so, with the actuation of a relay 12, 10 percent of the steam corresponding to the bias is cancelled while that equivalent to α percent is relieved frm the bypass valve, while the generator is cut off load or in isolated operation. In this manner, the turbine speed can be maintained constant.
