Abstract this paper introduces a new thermal station energy control system, which was accused of parameters for the work supply return water temperature, operation quantity for secondary circulating water flow, pensation signal as the outdoor temperature. for average temperature with outdoor temperature, backwater rate (compensation) adjustable, adjustable for backwater average temperature of the given initial value, the actuator is one with a prepared frequency control water circulating pump, variable frequency adjustable threshold limit. Compared with the traditional power control system, is accused of parameter selection is reasonable, runs stably is feasible and energy saving the economy. This article give system USES the necessary conditions.

水力平衡调节需要的热量由热力站通过二次网供给。热力站能量调节实质上是按照热用户需要的热量调节热力站输出的热量,或者说,热力站根据负荷变化改变输出的热量。这是热力站能量调节的宗旨。同时,热量输送载体二次网流量也需要随着负荷变化,以便节能,这是热力站能量调节的主要目的。
Hydraulic balance regulating needs to supply heat by thermal station through the work. Thermal station capacity control is essentially thermal heat adjustment to meet the needs of users according to the thermal output of heat, or thermal station according to the load change change the heat output. This is the purpose of thermal station energy regulation. At the same time, the heat transmission carrier flow also need to change as the load, so that energy conservation, the main purpose of which is thermal energy regulation.
