Thermoelectric decoupling system and method based on high-low bypass joint heating mode

The invention discloses a thermoelectric decoupling system and method based on a high-low bypass joint heating mode, and belongs to the field of thermoelectric systems. The thermoelectric decoupling system comprises at least one brake valve mounted on a pipeline in front of a high-bypass water spraying adjusting valve, at least two flow measuring devices mounted in a pipeline of a high-bypass attemperation water and steam system, at least one butterfly valve mounted on a pipeline between a low-pressure bypass and a condenser system, and at least two flow measuring devices in a pipeline of a low-bypass attemperation water and steam system. Steam is guided out of a low-bypass outlet of any unit to a heat supply network heater steam inlet main tube of all units, and the system is kept balanced through flow detection and flow control. According to the thermoelectric decoupling system and method based on the high-low bypass joint heating mode, a high-low pressure bypass system is creativelyutilized for guiding the
