虽然大电网的事故很少发生,且近代锅炉设计中考虑了快速恢复负荷的能力,但为使电站复役并入网内,锅炉机组仍需备有一套运行操作顺序。近代电网大多为瞬时性故障,而现代锅炉所具有的恢复蒸发量的能力更缩短了事故的持续时间。在大多数的电网事故情况下,锅炉的控制和辅机系统,系处于“发电-输电-配电”环节远离配电的一端,因而可能在数秒钟内无法感知系统的故障。然而,为了迅速发现故障并自动地处理,需有应急的恢复程序和控制设备。
Although incidents of large power grids rarely occur, and modern boiler design has taken into account the ability to quickly recover the load, in order to integrate the reentry of the power station into the network, the boiler unit is still required to have a sequence of operation and operation. Modern power grids are mostly transient failures, and the ability of modern boilers to restore evaporation further shortens the duration of the accident. In most cases of grid incidents, the boiler control and auxiliary systems are at the end of the “power generation - transmission - distribution” chain that is remote from the distribution and may not be able to sense system failures in seconds. However, emergency procedures and control equipment are required in order to detect faults quickly and handle them automatically.
