Characteristics of Intelligent Substation Relay Protection

According to the requirements of the “four characteristics” of relay protection (i., reliability, selectivity, sensitivity, and speed), once there is a fault within the power grid, it is necessary to accurately, quickly, and effectively limit it to the minimum range to avoid. Then, due to the particularity of historical statistical data, a weight calculation method combining analytical hierarchy process (AHP) and entropy weight method is adopted to eliminate subjective factors in the weight calculation process. Meanwhile, the equipment operation risk level was. Ontario Hydro developed the Integrated Protection and Control System (IPACS), with the first system installed in 1992. Substations are critical nexus points in the power grid, transforming high-voltage electricity to ensure its safe and efficient delivery from power plants to millions of end-users.

Relay protection quadrilateral protection characteristics

Quadrilateral characteristics is one of the most sophisticated and widely-used impedance-based relay protection schemes in modern electrical power systems. In this. Abstract—This paper analyzes factors affecting the performance of current polarized reactance elements and provides guidelines to ensure the security of Zone 1 quadrilateral distance elements. These relays may sometimes be set based in percentages of the line impedances, for example a typical setting for zone 1 is 80% of the impedance of the line in order to not reach the remote end, the zone 2 can. Other types of impedance relays are e. loss of synchronism protection, loss of excitation protection, or impedance automatics like fault locator. Also. Abstract—Quadrilateral distance elements can provide significantly more fault resistance coverage than mho distance elements for short line applications.
