Title: Overspeed preventive device for turbine control
Inventor: TAJIMA SHINICHI
IPC: F01D21/02
Filed: 1984-10-05
Abstract: PURPOSE:To prevent unintended outage of a plant, in which overspeed is precluded by rapid closing of valves when the acceleration in the revolutions of steam turbine exceeds a specified value, by furnishing a means to allow the valve not to be closed quickly by varying load. CONSTITUTION:As an acceleration sensor, a differential circuit 48 is furnished to sense the change in the speed per unit time in the number of revolutions N of a turbine, i.e. acceleration A, and its sensed value A is sent to a comparator 50 to be compared with the set acceleration Ao by an acceleration setting device 49; if A>Ao, a signal Q is given to rapidly closing such valves as an intercept valve. Another comparator 62 conmpares the number of revolutions of N of the turbine with the set speed Ns by a speed setting device 61; if N>Ns, an output is given to put a logical sum circuit 63 in ON state. At this time the above-mentioned signal Q is given to such valves as the intercept valve to close them quickly. If N<Ns, this signal Q is hindered from being output.
