SYSTEM AND METHOD FOR CONTROL OF A TCSC IN AN ELECTRICITY TRANSPORT NETWORK, SPECIFICALLY USING A LYAPUNOV APPROACH

摘要

The invention concerns a system and a method for command of a TCSC fitted to a high voltage line (40) in an electricity transport network. The system comprises: - a voltage measuring module (41), - a current measuring module (42), - a regulator (43) following a nonlinear command law, which receives the outputs of the two modules for measuring voltage and current, and a reference voltage corresponding to the voltage fundamental sought from the terminals of the TCSC, - an extraction module (44) for the command angle according to an extraction algorithm, - a command module (45) for thyristors (T1, T2) of the TCSC, which receives a zero current reference delivered by a phase lock loop giving the current position (46).
