牡丹江第二发电厂新装了两台哈尔滨汽轮机厂制造的 N-100-90/535型10万千瓦汽轮机。1号机于1981年5月投入运行,调速系统存在着附加保护提前在3240～3250转/分动作的缺陷,2号机也存在类似缺陷,附加保护在3355转/分动作。经过多次调整、试验,采取了一些可行的措施,解决了一些问题,现介绍如下。一、调速系统附加保护原理N-100型汽轮机的调速系统为机械液压式,主要由调速器、调速器错油门、反馈错油门,同步器及油动机等组成,如图1所示。
Mudanjiang Second Power Plant newly installed two Harbin Turbine Works manufactured N-100-90 / 535-type 100,000 kilowatts turbine. Unit 1 was put into operation in May 1981 and there was a defect in the speed control system that the additional protection was operated in advance at 3240 ~ 3250 r / min. The unit 2 also had similar defects and the additional protection was at 3355 r / min. After many adjustments and experiments, some feasible measures have been taken and some problems have been solved. First, the speed control system additional protection principle N-100 turbine speed control system for the mechanical hydraulic, mainly by the governor, governor wrong throttle, feedback wrong throttle, synchronizer and oil motive and other components, as shown in Figure 1 Show.
