Single phase Power control TE10P

Giuliano Raimondo 1 Details. Giuliano Raimondo 1 AuthorId: In railway transportation, single-phase 25kVHz electrification system is widely diffused especially for high-speed railway applications. In early ages, due to its very simple diagram, there was no necessity to integrate power electronics in substations. However, for the last decade, the interest in power electronic equipments raised since they can provide the solution for network optimization when traffic increases or when a difficulty is foreseen for a substation implementation.

Two types of devices are implemented monophqse on the French Railway Network: Reactive Power compensators and Voltage Unbalance compensators.

This thesis presents an investigation into new topologies based on the concept of “Chopper Controlled Impedances” CCI. Compared to existing solutions, the new topologies show interesting features in terms of semi-conductor losses reduction and volume of reactive components.

The manuscript is developed through three main parts: Firstly, the French railways system is introduced and the interest in installing power electronic compensators in substations is highlighted. After a brief description of currently used solutions, the CCI concept is presented: In the second part, the use of CCI structures in reactive power compensation is investigated.

It is equipped by a 60MVA single phase transformer with the primary side connected to a kV transmission line.

Based on the step-down or step-up functioning mode of CCIs, two topologies of reactive power compensator are presented. The converter design is developed on the base of a measurement campaign carried out at the substation. Numerical simulations using real current and voltage waveforms are presented.

Finally, experimental results carried out at the SNCF test platform on a 1. In the last part, the problem of voltage unbalance is treated.

As a case study, the substation of Evron is considered. It is a 32MVA substation connected to a 90kV transmission line.

Measurements carried out on the substation site allow the compensator design and the possibility to consider real waveforms for current and voltage in numerical simulations. Le manuscrit contient trois parties principales: Monday, March 26, – 3: Saturday, September 29, – 3: Wednesday, June 27, – 2: Power quality improvements in 25 kV 50 Hz railways substation based on chopper controlled impedances.
