Abstract

PURPOSE:To prevent the motoring at the time of parallel operation of the turbine generator system by raising the output of the generator to a value not to generate the motoring when operating the generators in parallel. CONSTITUTION:When a generation command (c) and parallel breaker closure signal (b) are inputted to an automatic control device 19, relays X1, X2 are operated, and output regulating interrupter X5 is operated. The interrupter X5 intermittently interrupts an output increasing relay X6 to thereby set the output setting unit X8 at increasing side, and the governor operating mechanism 15 is driven through a governor control unit 22. When the output of the generator becomes a value not to generate the motoring due to the head of the output of the generators and hydraulic pressure variation of iron pipes, a signal (a) is applied to the relay X3, which thus operates to maintain the output setting unit X8 at its position. Thus, the motoring of the generators at parallel operating time is prevented.
