Taken the thermal power plant super-heater temperature as research background, to explore a modeling method of high order with different capacity part, which can describe a class of nonlinear system effectively, the dynamic characteristic of super-heater temperature with controlled object can be described by a unified mathematic model which is with the same capacity characteristic, and taking full...
Dynamic characteristic of supercritical unit is complex. Its control technology is an important research task. This paper presents a mathematical model of coordinated control system controlled objects. For control characteristic of supercritical unit, design a generalized intelligent coordinated control system which made up of classical control, modern control, intelligence control and special measure...
Automatic generation control (AGC) is an essential requirement of modern power system automatic control. At present, slow response to AGC load demand is a serious problem existing in thermal power units taking part in AGC, which makes the control performance of power system AGC poor. The unit one and unit two of Yaomeng Power Co. Ltd., are all once-through boiler, its boiler-turbine coordinated control...
Supercritical-pressure coal-burning unit has lower coal-consumption & polluter and higher technology advantage, but it also have non-linear and multi-coupling issues in process control. A practical mathematic model was presented in this paper in order to analyze the controlled object. Combined the simulation data and the real unit operating data several times, the model was modified to a higher...
The validity of mathematical model direct impact the research result of the boiler-turbine coordinated control system. Based on the mechanism mathematical model and system identification method, this paper build a non-linear mathematical model of boiler-turbine coordinated controlled object. By deducing and comparing the corresponding differential equation with another non-linear mathematical model,...
Based on the excellence of mechanism mathematical model and system identification model, this paper established a mixed model of boiler-turbine coordinated control system (CCS), which combines mechanism analysis and parameter identification. To configure the model into a distributed control system (DCS) of the unit generator, by comparing the model parameters trend curve with the unit generator actual...
