Abstract
Due to the delayed inertia characteristics of the coal pulverizing system,it has a significant impact on the response rate of the boiler.Improving the hysteresis of the coal pulverizing system is of great significance for increasing the unit load rate.This paper analyzes the impact of variable speed control of the coal mill on the response characteristics of the unit through system modeling and data simulation,and designs a fast load control strategy for the unit based on the variable speed coal mill.The speed of the coal mill is controlled according to the load process and demand,maximizing the advantages of the variable speed coal mill to improve the unit's load rate response ability.The effectiveness of the strategy is verified through experiments.The test results show that the adoption of this control strategy on a unit equipped with a variable-speed coal mill can effectively improve the variable load rate of the unit,and the variable load rate of the unit can reach more than 3%Pe/min,which greatly improves the load response capability of the unit.关键词
