Transient Control Analysis of Power System by Dynamic Braking
초록
This paper analyzes the transient control characteristics of power system by dynamic braking. This method, one type of network switching, employs the injection of controllable shunt resistors at or near the generator bus after the disturbances. First, the power system is simulated mathematically for applying the dynamic braking. And the electrical transient control characteristics are considered by controlling the brake size and insertion time. Second, the mechanical torque of turbine-generator is calculted for the mechanical characteristics. This analysis results show that the electrical characteristics are improved but the turbine-generator shaft is impacted by brake switching. However, these problems can be solved by controlling the brake dynamically.
