Analysis of transient steady-state characteristics considering static eccentricity fault of synchronous condenser
The steady-state and transient reactive power compensation ability of synchronous condenser mainly depends on its steady-state synchronous reactance and transient reactance. When the rotor air gap static eccentricity fault occurs
the transient and steady-state reactance will change. Aiming at the way to accurately consider the change trend of transient and steady-state reactance parameters under the static eccentric fault state of large synchronous condenser
based on the definition of the transient and steadystate reactance parameters of the synchronous condenser and the electromagnetic relationship between the windings and the magnetic circuit structure inside the motor
the influence of the static eccentricity fault of the synchronous condenser on its transient and steady-state reactance was derived. Secondly
the finite element model was built based on the mechanical parameters of the synchronous condenser
and the transient and steady-state reactance parameters of the synchronous condenser were calculated by using the superconducting circuit method. The error between the finite element calculation results and the actual value of the synchronous condenser is within 5% . Finally
the finite element calculation of the transient and steady-state reactance of the down-regulated camera with different degrees of static eccentricity fault was carried out. The results show that with the increase of the degree of static eccentricity fault of the synchronous condenser
the steady-state synchronous reactance and transient reactance of the synchronous condenser show an increasing trend
which is consistent with the theoretical derivation results.
