Title: Heating steam pressure control method for reheat steam turbine and reheat steam turbine plant
Inventor: KUROSAWA ATSUHIRO
IPC: F01K13/02
Filed: 1995-05-30
Abstract: PURPOSE: To shorten the start time of a turbine by obtaining the value of thermal stress generated to a low pressure turbine from the low pressure turbine inlet part metal temperature, and controlling a heating steam pressure control valve so that this value does not exceed the specified value to the specific life. CONSTITUTION: The low pressure turbine inlet part metal temperature 13 is detected and taken into a thermal stress computing element 26. The specific life consumption of a low pressure turbine 5 is computed from thermal stress generated to the low pressure turbine 5, and the thermal stress value is determined from a life cycle. This value is compared with the thermal stress limit value of a thermal stress limiter 28 by a thermal stress comparator 27. The compared result is sent as a thermal stress ratio to a thermal stress ratio - heating steam pressure change rate setter 25, and the optimum heating steam pressure change rate is determined according to the operating state of the turbine. Turbine load from a load detector 21 is sent as the heating steam set pressure to a heating steam pressure setter 23. The heating steam pressure, a change rate setting signal and the signal of an actual heating steam pressure detector 14 are compared by a heating steam pressure comparing part 19 to compute the deviation, and a heating steam pressure control valve 8 is controlled in response to this signal.

Title: Power-factor improving control system
Inventor: SAKAI KUNIZOU
IPC: H02J3/18
Filed: 1979-10-17
Abstract: PURPOSE: To make good power-factor control possible, by using a computer to operate effectively the phase advance function of the power-factor improving capacitor.  
     CONSTITUTION: Computer 1 takes in required information from reactive power meter 18, power-factor indicator 19, and so on through process input/output device  2 to calculate a taking-in power-factor control quantity. Next, the decision processing for necessity of power-factor control is performed. At this time, hysteresis is provided for switching of the capacitor not to turn on and off the capacitor even if load fluctuation is generated near the point or the shut off point to change reactive power. If it is decided that power-factor control is necessary, computer 1 determines the capacitor to be switched, for example, capacitor 13 and actuates relay circuit 3 and breaker 8. In this case, since the power-factor indicator is used only for decision of phase advance and lag, reliability of data taken into computer 1 is enhanced, and accurate power-factor control is possible. Since hysteresis is provided, the operation of the breaker for some load fluctuation can be prevented.
