Limiting measures of capacitance current in long-distance cable line
WANG Zhen
Abstract：For the problems of long-distance cable currents such as increased power loss, reduced power factor, and disconnected switches that cannot be connected to no-load lines, the currents of the cable lines are analyzed to obtain the capacitance of the no-load and light-load lines. Excessive currents such as capacitive reactive power are the root cause of the above problems. When the no-load line capacitance current exceeds 5A, shunt reactor limits can be used on the circuit breaker side. When the no-load line capacitance current does not exceed 5A, but the light-load operation is sent back to the grid for reactive power, a shunt reactor can be installed on the high-voltage bus to limit or use the main transformer low voltage side static var generator(SVG)limit.
