Analysis and Improvement to Coordination Control Circuit of 2×350MW Supercritical Units

摘要

The paper introduces the characters of coordinated control system which belongs to 2×350MW supercritical air cooling heating units in a power plant. Meanwhile this article analyzes the control strategyies and the characters of main control circuits of boiler units and steam turbines respectively. The request of supercritical units running steadily and reacting quickly is satisfied by employing the technique of static feed-forward and so on.
