摘要

This paper presents a method which can equivalently arrange the capacitance distribution along with the winding of the generator on the terminal and neutral respectively in a reasonable partition, particularly for a type of high-voltage graded insulated cable-wound generator, powerformer. This method can be used to compensate the capacitive current wholly to improve the reliability of the differential protection. It is proved that the capacitive current in the case of normal operation, external fault and internal fault can be calculated using the same dividing method. The formula of the partition coefficient is provided and the characteristic of the coefficient is explored by MATLAB software.
