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).

The present invention relates to a system and a method for controlling at least one voltage converter with several cells (12) in series, comprising an AC part (13) and a DC part (14), in which the AC input voltage (Vei) of each cell is determined directly by using a fast-dynamics current-control loop (20) relating to the AC part (13), and a slower-dynamics voltage-control loop (21) relating to the cells (12), which delivers an active power ψ i such that: formula (I) where: • K 1zi and K 2zi are positive setting gains, • C i : continuous capacitance of the capacitor Ci of each cell, • R pi : losses associated with each cell, • Z i - ref : referenced value Zi=(U DCi ) 2 , U DCi being the continuous voltage across the terminals of the capacitor C i , • E zi : such that E zi =Z i -Z i-ref .
