摘要

基于发电机组一次、二次调频综合性能的机组控制性能标准(unit control performance standard

UCPS)

通过对电网能量状态和火电机组能量特性分析

综述了网源不同的能量状态对电网和机组的影响

探索了达到网源双赢的机组侧负荷频率控制策略。该策略利用燃煤机组的“能差”

主动参与电网调频、“知能善用”地适应电网侧自动发电控制(AGC)变负荷任务

充分发挥机组良好的调频调功性能。通过对同类型机组的试验对比分析

得出机组侧应用UCPS控制策略

既对电网频率控制有益

又提高机组安全、稳定运行水平

降低机组运行成本

从而达到源网协调控制电网频率总体最优的目标。

Abstract

Based on the unit control performance standard(UCPS)considering the comprehensive performance of units primary and secondary frequency modulation

this paper comprehensively explains the influence of different energy states on power grid and generator units through an analysis of energy states on power grid and energy characteristics for ultra suoercritical units. And a study is made on the load frequency control strategy leading to win-win for power grid and generator units. This strategy utilizes the coal-fired units “energy deviation” to actively participate in peak regulation of the grid and appropriately assign the automatic generation control(AGC)load modulation task

which can exploit the fine frequency regulation performance of units. Through the experimental comparison and analysis to the same type units

it is also beneficial to improving the frequency quality of power grid and the stability and economic performance of the units using UCPS control strategy to realize both power grid and generator units coordinated control grid frequency overall optimal target.
