Research of Primary Frequency Regulation Control Strategy Based on Stimulative Simulation System

Abstract:

The once-through boiler is widely used in high capacity unit currently, however its heat storage capacity is small, and the unit’s response lags during primary frequency regulation. These all lead to the limited frequency regulation ability. For the purpose of studying the primary frequency regulation optimized control strategy, this paper established a primary frequency regulation characteristic simulation platform based on stimulative simulation system. Using this platform, it proposed an improved program for once-through boiler’s primary frequency regulation control strategy. It’s supposed to cover the insufficient heat storage capacity of the boiler by introducing the differential feed forward signal of the fuel supply and water flow. The simulation result shows that the proposed control scheme effectively improves the speed of primary frequency regulation. This platform provides a reliable basis for once-through boiler’s primary frequency regulation control strategy, and also has a certain guiding significance for further study.
