预测模糊控制在液化天然气调峰系统的应用
The application of predictive fuzzy control in the liquefied natural gas peak-shaving system
摘要
Abstract
LNG(liquefied natural gas) gasification station resently usually separates the tank pressure adjustment from the peak‐shaving technique ,so the system is relatively complex and need a large in‐vestment .Through demonstration research ,a system scheme which was combined by the tank pres‐sure adjustment and peak‐shaving technique was proposed .Aiming at the characteristics of large lag , time‐varying and nonlinear in the storage tank pressure system ,the control strategy by taking the generalized predictive control algorithm as the core and the fuzzy control as dynamic feedback compen‐sation was adopted .Accurate pressure control of the storage tank was realized combining with the characteristics of DSP and FPGA device for high‐speed data processing .In system practical operation , the control was proved with the advantages of quick adjustment ,real‐time and strong robustness . And the results showed that the outlet pressure fluctuation of the gasification station was less than 3 . 5% ,and it had a good peak‐shaving effect .This system has the characteristics of simple structure , strong anti‐interference ability and good peak‐shaving effect .And it provides a new idea for city gas peak‐shaving system .关键词
