Secondary side temperature control framework and method for heating system of heat exchange station

Abstract

The invention discloses a secondary side temperature control framework and method for a heating system of a heat exchange station. A first temperature parameter input end and a second temperature parameter input end of a double-input single-output temperature controller are correspondingly connected with a secondary side water supply temperature transmitter arranged on a secondary side water supply main pipe and a secondary side water return temperature transmitter arranged on a secondary side water return main pipe correspondingly, a control instruction output end of a double-input single-output temperature controller is connected with each controlled electric control valve arranged on each primary side water return branch pipe, so that the opening degree and the angular speed of the electric control valves are adjusted based on the secondary side supply and return water temperature difference deviation value and the temperature difference change rate, and the purpose of adjusting the secondary side supply and return water temperature of the heating system of the heat exchange station is achieved.

Description

technical field [0001] The present invention relates to the temperature control technology of the secondary side of the heating system of the heat exchange station, in particular to a temperature control framework and method for the secondary side of the heating system of the heat exchange station. The second temperature parameter input end is respectively connected to the secondary side water supply temperature transmitter set on the secondary side water supply main pipe and the secondary side return water temperature transmitter set on the secondary side return water main pipe, and the dual input The control instruction output end of the single-output temperature controller is respectively connected to each controlled electric control valve set on each primary side return water branch pipe, so as to adjust the electric control valve based on the temperature difference deviation and temperature difference change rate of the secondary side supply and return water. The size of ...

Problems solved by technology

The inventor found that under the current technical conditions, the heating system control of the heat exchange station mostly relies on the manual control of the on-site operation and maintenance personnel, and the automatic control also mostly stays in the secondary water supply temperature fixed value control and time period control, and the control accuracy is low, resulting in heat exchange. The phenomenon of low thermal efficiency and poor heating quality of station heating system directly leads to low heat user satisfaction and serious energy waste
