Abstract

An overhead transmission line temperature-rising method based on parallel capacitor compensating reactive power source is proposed. The method is based on the characteristics of sinusoidal AC and the theory of parallel capacitor compensating reactive power source within electric power grid. The theoretical derivation and wiring diagram of this method is given in this paper. The novel temperature-rising method is based on inputting reactive current at the terminal of transmission line. The probable conditions of system resonance caused by parameters variation during the overhead transmission line temperature-rising operation is analyzed theoretically and the resonance suppression measures and methods are given. Through the on-site thermal experiment of 10kV power transmission line, the real-time data of the current I, active power P and reactive power Q are obtained, which verifies the theoretical efficiency and feasibility of the temperature-rising method.
