Research on Performance Evaluation Model Method of Boiler Turbine Network Coordinated Control at Thermal Power Plant

火电厂炉-机-网协调控制性能评价作为鉴定火电厂采用协调控制策略和算法的优劣的基础,其模型的好坏直接关系到电网的电能质量、火电厂的锅炉使用寿命和运营成本等。从协调控制算法对系统调频、潮流分布和锅炉使用寿命进行研究和分析,构建了独立的影响模型计算方法和综合评价模型,通过该模型可以快速直观地对不同的协调控制算法在各个方面的性能及综合表现进行评价,为调整和优化火电厂协调控制策略和方法提供基础。

Thermal power plant boiler-machine-network coordinated control performance evaluation serves as the basis for identifying the quality of coordinated control strategies and algorithms used in thermal power plants.The quality of its model is directly related to the power quality of the power grid,the service life of the boilers of thermal power plants,and Operating cost,etc.,this paper studies and analyzes the system frequency modulation,power flow distribution and boiler service life from the coordinated control algorithm.First,an independent influence model calculation method is constructed from these three aspects,and then based on the fuzzy comprehensive evaluation analysis method,A comprehensive evaluation model is constructed,which can quickly and intuitively evaluate the performance and comprehensive performance of different coordinated control algorithms in various aspects,and provide a basis for adjusting and optimizing the coordinated control strategies and methods of thermal power plants.
