Physical Model Study of the Thyristor Controlled Series Compensator

This paper describes the design and application of a 1.0 kV TCSC physical model. As a general platform for study, the parameters of main circuit in this device can be adjusted to the different length of transmission line, the hierarchical structure and the corresponding modular structure of TCSC controller are more flexible and liable to carry out the study on control strategies. Various disturbances and operation modes are tested on the platform and it has the capability to carry out measurement, protection and control schemes in real-time. The experiment results show that the fast impedance control, damping the power oscillation and the accurate transition between inductive and capacitive modes can be realized on this platform
