| description | The invention provides an automatic ultrahigh tension long-distance transmission line malfunction load shedding system and method. The ultrahigh tension long-distance transmission line malfunction load shedding system comprises a line malfunction load shedding device, a coordinated control system, a boiler and a steam engine control system. The line malfunction load shedding device generates a line malfunction fast load down instruction and a sliding pressure-constant pressure instruction. A load instruction processing loop and a main steam pressure processing loop in the coordinated control system send a load target instruction and a main steam pressure target instruction to a main engine and boiler controller after receiving the instructions. The main engine and boiler controller sends a boiler combustion ratio reducing instruction to a boiler control system to remove a coal mill and sends a constant pressure maintaining instruction to the steam engine control system, and constant main steam pressure runnin |
