The Optimized Design of Coordinated Control System Based on Load Feedforward and Unidirectional Decoupling

In actual operation, the rising load will lead to the reduction of pressure because of the long delay of the boiler. It can lead to the main steam pressure lockout in severe cases. The proposed model is derived by the principle analysis of control object and the introduction of load feedforward. The...

Summary:In actual operation, the rising load will lead to the reduction of pressure because of the long delay of the boiler. It can lead to the main steam pressure lockout in severe cases. The proposed model is derived by the principle analysis of control object and the introduction of load feedforward. The unidirectional decoupling method is verified by the simulation in Matlab. Not only the decoupling has achieved good results, but also the performance of the control system has been greatly improved. All the above study are based on a 1000MW power unit.
