摘要

为了有效实现电站的优化运行

以满足电站最大限度的节能增效的要求

需要对电站实际运行状态(简称电站状态)的稳定性能进行评价。为此

研究了影响电站状态波动的内在因素及与控制作用的关系

并用统计回归的方法分析其波动的周期特性

提出一种实用的稳定性评价指标。以600MW机组功率信号的历史数据为例

分别评估其在400MW、500MW和600MW附近30组工况的稳定性能

证明了该评价指标的有效性和实用性。

Abstract

In order to effectively realize optimized operation in power plant

so as to fullest possibly satisfy the requirements of energy-saving and efficiency-enhancing in the power plant

it is necessary to evaluate the practical operating state stability in the power plant(for short it is called "plant state stability").For this

the inherent factors affecting fluctuation of the "plant state stability" and their relation with the control effect have been studied

and the periodic characteristics of the fluctuation being analysed by using a statistic regression method

putting forward a practical evaluation index of the stability.Taking the historical data of power signal for a 600 MW unit as example

the stability of thirty operating conditions nearing 400 MW

500 MW

and 600 MW has been evaluated respectively

verifying the effectiveness and practicability of the said evaluation index.
