双抽汽轮机热电负荷解耦协调控制研究
Research on the thermo-electric load decoupling and coordination control of double exhaust steam turbine
摘要
Abstract
In the research of control of double extraction steam turbine thermal-electric load coordinated,serious coupling relationship exists among the output of power load,pumping the high pressure heat load and low heat load,change of any load will have different degrees of impact on other loads,due to the frequent fluctuation of heat and electricity load,thus af-fecting the control performance of the whole system.In order to solve the above problems, this paper proposed a multi variable decoupling control scheme which combines the feed-for-ward decoupling and simple fuzzy neural network.The system dynamic and static decoupling is achieved through feed-forward compensation.The fuzzy control rules is adj usted in real time by neural network.Consequently,the control effect and adaptive ability of the system are improved.Matlab simulation results show that the improved control method solvest he strong coupling problem of the power load,improves the robustness and adaptability of the system and has great practical value.关键词
