汽轮发电机组普遍采用带有差调节特性的调速系统,习惯用四象限环状座标图表征其静态特性。我们认为有关静态特性的各项问题,实质上是座标图中特性线的形状、位置及计算的问题。试采用描述四象限图线的解析式(应用解析几何学的原理)来研究这些问题。根据这一方法,得出调速系统的转速与功率的关系式:即调速系统静态特性方程式。本文简介该式在计算与现场调整中的有关应用。
Turbine units commonly used speed regulation system with poor adjustment characteristics, customary four-quadrant ring coordinates of its static characteristics. In our opinion, the questions about the static characteristics are essentially the shape, location and calculation of the characteristic lines in the graph. Trying to use analytical four quadrant lines (analytical principle of analytic geometry) to study these issues. According to this method, the relationship between the speed and the power of the speed control system is obtained: that is, the static characteristic equation of the speed control system. This article describes the type in the calculation and on-site adjustment of the application.
