Computer Studies of Dynamic Shunt Compensation Performance

Computer studies for dynamic shunt compensation are useful in determining the performance of the compensating device as well as the system into which it is connected. Due to the significant amount of power electronics in modern dynamic compensators, electromagnetic transients simulation of both the off-line and real time variety is widely used for aspects such as controller tuning, harmonic resonance analysis, determination of operating limits and interaction with other dynamic devices in the network. For studying the impact of shunt compensation on the stability of large system, transient stability modelling can be used. Small signal analysis although less accurate, provides insight into optimal placement of the compensation as well as controller gain selection
