Embodiment Construction
[0075] The present invention will be further described below in conjunction with the accompanying drawings of the description.
[0076] Taking a certain type of 15kVA dynamic model unit as the implementation object, using the above-mentioned on-site parameter setting method, and comparing whether the unit has PSS or not, the practicability, effectiveness and scientific nature of the specific embodiment of the present invention are further explained.
[0077] In this embodiment, the unit adopts self-shunt excitation mode, and the main rated parameters of the generator are as follows: rated apparent power 15kVA, rated active power 13.5kW, rated machine terminal voltage 380V, direct axis synchronous reactance (unsaturated value) and quadrature axis synchronous The reactance (unsaturated value) is 108.25%.
[0078] 1. Field test of non-compensated hysteresis characteristics of generator excitation system
[0079] The working conditions of the unit during the field test are as fol...
