Series Compensation for Hydro-Quebec Long Distribution Lines.

Abstract

The paper focuses on the use of series compensation in a Hydro-Quebec long distribution line. The basic theory of a series compensation is outlined together with operation network constraints that should be respected in practical applications. The study is done on a 60km radial distribution line supplying both industrial and residential customers. Three levels of compensation rate have been tested, 0% (non compensated), 36% and 60% in both frequency response and time domains. Simulation results greatly attest the effectiveness and the practicability of the series compensation of long distribution line in transient and steady state improvement of the voltage profile and fluctuation reduction
