汽轮机是火力发电设备三大主力(锅炉、汽轮机、发电机)之一。而作为汽轮机系统之一的调节系统则是整个机组的大脑,因此,它的失灵必将危及汽轮机运行的安全。由此可见,汽轮机调节系统的可靠与否则对整台机组的性能优劣起了重要的作用。所以,我们站在设计的角度上来考虑,当产品的可靠性与效率发生矛盾时,我们是宁愿使效率略低而必须首先确保其可靠性的。因为,如有一台机组(30万千瓦)由于故障而造成强迫停机一天,就会少发720万度电,给电厂造成一定经济损失。所以发
Turbine is one of the three main power generation equipment (boilers, steam turbines, generators). The regulation system which is one of the turbine systems is the brain of the whole unit, therefore, its failure is bound to endanger the safety of the steam turbine. Thus it can be seen that the reliability of the steam turbine governing system plays an important role in the performance of the whole unit. Therefore, we stand in the design point of view, when product reliability and efficiency of the conflict, we would rather lower efficiency and must first ensure its reliability. Because, if a unit (300,000 kilowatts) due to failure caused by a forced shutdown one day, it will send 7.2 million kilowatts less, causing some economic losses to the power plant. So hair
