Three-phase autonomous reluctance generator

The three-phase autonomous reluctance generator is analysed. It is shown that the linear mathematical model of the generator in the rotor reference frame is composed of time-invariant differential equations. The effect of the load on the stability of the system is considered. Simple equations relate the reluctance generator parameters and the external load. These equations are adopted as a basis for new methods of finding the machine parameter characteristics. The presented new methods of the machine parameter measurement and the known conventional methods are compared. The steady-state value of the reluctance generator variables can be found by solving algebraic equations, without resorting to numerical methods.
