Abstract

Modern trends in designing generators for independent power plants require mass and volume reduction by means of increasing electromagnetic load. Conflicts arise with operational requirements regarding voltage drop limitation under sudden load increase. Practical methods to solve the problem at the present stage of generator design and manufacture are suggested. Several methods are outlined to limit generator reactances Open image in new window by selecting electromagnetic load levels, as well as choosing the geometry of stator teeth zone, of rotor poles, of damper winding. Besides, the problem of asynchronous motor starting from generators of independent power plants, working at no-load prior to the starting of the motor has been investigated in the article. Some additions to the standards for independent generators are proposed.
