【Abstract】 The mechanism of power line parameter test interference of transmission line is analyzed, and through the electrical transient analyzer program( EMAP), the interference level of the power-frequency parameter measurement of Langfang-Quancheng UHV transmission line is calculated. The calculation method is proved to be accurate by practical measurements.Calculation results can provide a theoretical guidance for power-frequency parameters measurement scheme and guarantee the safety of personnel and equipment. At the same time, the economic loss caused by adjacent transmission line power failure is avoided.更多还原
