Application Research Of Coordinated System For Power Generation Units Based On The Two Rules

The State Grid published the’two rules’files, in order to enhance network security, high-quality operational capabilities, maintaining the order of the electricity market,. The’two rules’assesses the comprehensive index KP value of the thermal power units AGC, from the AGC investment rate of the units, the regulation accuracy, the regulation rate and the response time.In this paper, with power generation company limited in Datong of Guodian on the7th machine600MW coordinated control system for the study, to conventional coordination control system improvements, in order to improve the performance of the grid on the AGC regulation indicators. Optimized the coordination control logic of the unit power plant boiler side and turbine side, and condensate throttling have been experimented, through changing the low piping of the condenser. The above work is combined with the use of classical control theory in the field, and condensate throttling technology and coordination control systems complement each other input. This paper analyzed a large number of on-site data, based on the researcher of the temperature of the unit mill outlet, coal coefficient deviation, relationship between burning of coal and AGC regulation performance indicators KP value, and the relationship between coal coefficient and the coal mill inertia.
