Projet 1A by Berengere Dosbour on Prezi

The concept consists of charging capacitors in parallel followed by reconnection hachuer series of the capacitors to create higher dc voltage. Ticonal magnet – bar: All items in eScholarship McGill are protected by copyright with all rights reserved unless otherwise indicated. The simulated system comprises six VSC terminal stations, the Marx offshore station with an offshore wind farm and the dc power flow controller.

PED 3-phase thyristorised rectifier module, assisted inverter, free-wheel diode.

Hacheru resistors located in the branches enable to display the currents. PED Study of the main optoelectronic sensors, applications such as: Parallel resistors are located in the branches in order to display the current on the oscilloscope.

Equipment for Higher and Technical Education. PAM Possible overhead projection during experiments. The challenge is to bridge the two dc voltages without ac transformers.

VLV step-down thyristorised chopper – Training module ref: VLV 1-phase thyristorised rectifier – Training module ref: The integration of an offshore wind farm into a multiterminal HVDC system is also studied.

By using a dc collector network for the aggregation of power produced by the wind turbines, the high civil engineering cost of an offshore platform to support heavy ac transformers required by the converter station for HVDC transmission can be avoided. For offshore wind farm application, the Marx survoltteur converter is combined with a step-up converter to form the Marx offshore station which bridges the 10kV dc collector network to the kV HVDC transmission line.
