火力发电机组一次调频问题分析及解决方案

摘要

并网机组的一次调频性能的优劣直接影响电网频率的稳定，以目前火电机组调频功能中出现的主要问题作为研究对象，并对机前压力、转速不等率提出了具体可行的修正方案。%The performance of primary frequency compensation of thermal power generating units taking part in power grid is good or bad which may bring a direct impact on the stability of the power grid frequency. The main problem from the function of primary frequency compensation about thermal power generating units is studied in this paper, and feasible rectification solution for the pressure in front of turbine and steady-state speed regulation is proposed.
