Abstract EN
Transient effects such as overvoltage and inrush currents will be caused due to opening and closing the switchgear at random phase.
Phase-controlled technology present in recent years, which is restricted by the operation dispersion of actuator, can limit the transient effects.
And the dispersion of the switchgear with a permanent magnetic actuator (PMA) is small.
Therefore, the research of mathematical method and position control in this paper is based on the PMA.
Firstly, the dynamic mathematical method and simulation system established in MATLAB are used to improve the design of the PMA owing same type.
Secondly, simulation with the use of improved fuzzy algorithm is carried out.
And an optimized self-adaptive fuzzy algorithm is obtained in the simulation process which can be used to trace the given displacement curve.
Finally, a large number of tracing experiments have been done on the 35 kV breaker prototype to verify the effectiveness of the algorithm.
In the experiments, the closing time of breaker can be stabilized within ±0.5 ms when capacitor voltage and capacitance change.
These results prove that the mathematical model and the fuzzy algorithm are effective and practical.
