ORGANIZATION OF POWER DIRECTIONAL ELEMENT OPERATION IN MICRO-PROCESSOR CURRENT DIRECTIONAL PROTECTIONS
Abstract
The paper considers method for organization of power directional element operation in micro-processor current directional protections. The investigation of the proposed method has been executed with the help of computer program which is based on an algorithm of power directional element operation. The algorithm is built upon reference formation of orthogonal voltage components in accordance with measured references of orthogonal current components.
The proposed memory method for organization of the power directional element operation makes it possible not only to eliminate “dead voltage zone” but to ensure permanent control over power direction. The frequency dependence of the proposed method which is revealed in the process of calculative experiment can be neutralized by frequency correction.
