摘要
随着各区域电网"两个细则"的颁布,电力系统对火电机组的要求越发严格,使火电机组受到了很大的经济影响。为了使多变量控制系统性能评价理论和工程实际相结合,研究改进了多变量系统的协方差评价指标,并对"两个细则"AGC (Automatic Generation Control)的考核方式进行了分析和总结,提出了负荷控制系统改进的协方差指标和基于"两个细则"的经济性指标,通过加权运算来对负荷控制系统做出综合评估。利用仿真试验及现场数据,进行机组负荷控制系统评价方法的确立和验证,结果表明评价方法合理、有效。
With the promulgation of the"two detailed rules"of regional power grid,the requirements by power system thermal power units are more and more strict,and has greatly affected their economic development.In order to combine the performance evaluation theory of multivariable control system with the engineering practice,the covariance index of multivariable control system is improved,and the assessment method of AGC(Automatic Generation Control)is analyzed and summarized.The improved covariance index of load Control system and the economic index based on the"two detailed rules"are proposed,and the comprehensive evaluation of load Control system is made through weighted operation.Simulation test and field data are used to establish and verify the evaluation method of unit load control system.The results show that the evaluation method is reasonable and effective.
