연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A technique of controlling a steam generating boiler system includes dynamically tuning a rate of change of a disturbance variable (DV) to control operation of a portion of the boiler system, and in particular, to control a temperature of output steam to a turbine. The rate of change of the DV is dynamically tuned based on a magnitude of an error or difference between an actual and a desired level of an output parameter, e.g., output steam temperature. In an embodiment, as the magnitude of the error increases, the rate of change of the DV is increased according to a function f(x). A dynamic matrix control block uses the dynamically-tuned rate of change of the DV, a current output parameter level, and an output parameter setpoint as inputs to generate a control signal to control a field device that, at least in part, affects the output parameter level.

1. A method of dynamically tuning control of a steam generating boiler system, comprising: determining, by an error detector, a presence of an error corresponding to a temperature of output steam, wherein the output steam is generated by the steam generating boiler system for delivery to a turbine, and the determination of the presence of the error is based on a magnitude of a difference between a signal indicative of a measured temperature of the output steam received at the error detector and a signal indicative of a setpoint received at the error detector;providing, by an output of the error detector to a dynamic matrix controller of a control loop of the steam generating boiler system operating to control the temperature of the output steam, a signal corresponding to the error;receiving, at the dynamic matrix controller, (i) the signal corresponding to the error provided by the output of the error detector, (ii) a signal indicative of a rate of change of a disturbance variable generated by a device used in a portion of the steam generating boiler system, the portion of the steam generating boiler system excluding any devices included in the control loop, (iii) the signal indicative of the measured temperature of the output steam, and (iv) the signal indicative of the setpoint;adjusting, by the dynamic matrix controller based on the signal corresponding to the error, the signal indicative of the rate of change of the disturbance variable;generating, by the dynamic matrix controller, a control signal based on the adjusted signal indicative of the rate of change of the disturbance variable of the portion of the steam generating boiler system; andcontrolling, based on the control signal, a manipulated variable of the control loop of the steam generating boiler system to thereby control the temperature of the output steam. 2. The method of claim 1, wherein determining the presence of the error corresponding to the temperature of the output steam comprises detecting a difference between the signal indicative of the setpoint and the signal indicative of the measured temperature of the output steam. 3. The method of claim 1, wherein adjusting the signal indicative of the rate of change of the disturbance variable based on the signal corresponding to the error comprises adjusting the signal indicative of the rate of change of the disturbance variable based on an aggressiveness of tuning determined based on the magnitude of the difference between the signal indicative of the setpoint and the signal indicative of the measured temperature of the output steam. 4. The method of claim 3, wherein adjusting the signal indicative of the rate of change of the disturbance variable based on the aggressiveness of the tuning determined based on the magnitude of the difference between the signal indicative of the setpoint and the signal indicative of the measured temperature of the output steam comprises increasing a magnitude of an adjustment to the signal indicative of the rate of change of the disturbance variable as the magnitude of the difference between the signal indicative of the setpoint and the signal indicative of the measured temperature of the output steam increases. 5. The method of claim 4, wherein adjusting the signal indicative of the rate of change of the disturbance variable based on the aggressiveness of tuning based on the magnitude of the difference between the signal indicative of the setpoint and the signal indicative of the measured temperature of the output steam further comprises decreasing the magnitude of the adjustment to the signal indicative of the rate of change of the disturbance variable as the magnitude of the difference between the signal indicative of the setpoint and the signal indicative of the measured temperature of the output steam decreases. 6. The method of claim 1, further comprising: providing the signal indicative of the rate of change of the disturbance variable to a first input of the dynamic matrix controller, andproviding the signal corresponding to the error to a second input of the dynamic matrix controller; andwherein adjusting the signal indicative of the rate of change of the disturbance variable is performed by the dynamic matrix controller based on the signals received at the first input and at the second input. 7. The method of claim 1, further comprising providing a signal indicative of a magnitude of the error to an input of a function block, modifying the signal indicative of the magnitude of the error using a function included in the function block, and generating an output of the function block based on the modified signal indicative of the magnitude of the error; andwherein adjusting the signal indicative of the rate of change of the disturbance variable based on the signal corresponding to the error comprises adjusting the signal indicative of the rate of change of the disturbance variable based on the output of the function block. 8. The method of claim 7, further comprising: providing the signal indicative of the rate of change of the disturbance variable to a first input of the dynamic matrix controller,providing a signal indicative of the output of the function block to a second input of the dynamic matrix controller; andwherein adjusting the signal indicative of the rate of change of the disturbance variable based on the output of the function block comprises adjusting, by the dynamic matrix controller, the signal indicative of the rate of change of the disturbance variable based on the signals received at the first input and at the second input of the dynamic matrix controller. 9. The method of claim 1, wherein: controlling, based on the control signal, the manipulated variable of the control loop of the steam generating boiler system to thereby control the temperature of the output steam comprises providing the control signal to a field device of the control loop of the steam generating boiler system; andthe field device corresponds to one of a plurality of sections of the steam generating boiler system, the plurality of sections including a furnace, a superheater section and a reheater section. 10. The method of claim 1, wherein adjusting the signal indicative of the rate of change of the disturbance variable of the portion of the steam generating boiler system includes adjusting respective values of respective signals indicative of respective rates of change of at least one of: a furnace burner tilt position; a steam flow; an amount of soot blowing; a damper position; a power setting; a fuel to air mixture ratio of a furnace of the steam generating boiler system; a firing rate of the furnace; a spray flow; a water wall steam temperature; a load signal corresponding to one of a target load or an actual load of the turbine; a flow temperature; a fuel to feed water ratio; the temperature of the output steam; a quantity of fuel; a type of fuel, another manipulated variable of the portion of the steam generating boiler system, or a control variable of the portion of the steam generating boiler system.
