Based on the distribution parameters equation of long-distance transmission lines, which is expressed in phasor form, the paper proposes a discretization equation model, analyzes the protection of EHV transmission lines with shunt reactors by applying power balance principle and then the power balance protection criterion is determined. The power balance protection method, which is based on discretization equation of long-distance transmission lines, maximizes the use of the fault information such as voltage and current, etc. In this way, the fault of EHV transmission lines with shunt reactors can be removed accurately and quickly. On the other hand, this method is more convenient for modern microprocessor protection to process the discrete data and improve the power system performance after the criterion of power balance protection is determined. Results of EMTP simulation have demonstrated that under various fault conditions of EHV transmission lines with shunt reactors the power balance protection method has higher sensitivity and reliability and can be applied to identify the internal or external fault correctly.
