CONTROL SYSTEM AND METHOD FOR A TCSC IN AN ELECTRIC ENERGY TRANSPORT NETWORK IN PARTICULAR USING A SLIDING-MODES APPROACH

摘要

The invention relates to a system and method for controlling a TCSC available on a high-voltage line (40) of an electrical energy transport network. The system comprises: - a voltage measurement module (41), - a current measurement model (42), - a regulator (43) according to a nonlinear control law, which receives as input the outputs of the two modules voltage and current measuring device, and a reference voltage corresponding to the fundamental voltage of the voltage to be obtained at the terminals of the TCSC, - a module (44) for extracting the control angle according to an algorithm d extraction, - a module (45) for controlling thyristors (T1, T2) of the TCSC, which receives a reference of zero current delivered by a phase locked loop gives the position of the current (46).
