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

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 a
