To improve precision for model identification result of pumped storage motor, a kind of multivariable bilinear subspace recursive likelihood identification for pumped storage motor is put forward. Firstly, pumped storage motor magnetic filed equation is given, pumped storage motor model based on extension Kalman Filter is established, two-set identification models are constructed by coordination by...
Base on a prototype of the 130 kw/5 kv high voltage generator, the system simulation model is set up for the generator stator windings suddenly three-phase short-circuit failure and loss of excitation failures. The dynamic simulation compared with experiment on DJ18-1 synchronous generator, it reaches conclusion that the system simulation model is correct. The current of the high-voltage generator...
In order to study the static stability limit of high voltage generator, a mathematical model at high voltage generator leading phase operation is proposed; the calculation results of high voltage generator of the electric quantity of reactive power, terminal voltage, terminal reactive, terminal power angle are obtained at the static stability limit by using the analysis with constant active power...
