Automatic control system of heat-POWER PLANTS WITH CORRECTIVE ACTION FOR VALVES REGENERATIVE steam extraction

摘要

The invention relates to heat power engineering and can be used in thermal power stations (TPS) with different heat power plants, in particular with kotloparoturbinnymi (KPTU and combined cycle power plant (CCPP), to improve their maneuverability. Achievable result utility model is to provide an effective system of primary and secondary thermal power setting power control using control valves for steam regeneration selections. The inventive automatic regulation system Nia power selective power control (OPC) operating to increase the capacity when fully open control valves of the steam turbine (RKPT) by covering selected control valves (ORK) mounted on the fume regenerating selections comprises a nonlinear element (NE) deadband reference for integrating controller operation as a whole and its output connected to the parallel connected regulators to each regenerative steam line selection, and each of said controllers comprises sequentially cos union of NEs forming job entry to the work and the position of executive JWC appropriate selection proportionally predetermined unbalance power generator unbalance signal setpoint and current values ​​of the position actuator JWC and PD-controller, whose output is connected to the corresponding RCO, wherein the entrance to the HLR connected element " ban-less ", which is connected to the input of limit switches" more "RKPT.
