Numerical Relay Development Environment 1) Essential Relay Hardware- programmable through IDE, 2) Test setup: Two 3 Phase Over current & Earth fault relay (1A/5A/15A) is to be provided for protection with PC Interface facility (Suitable to interconnect–IEC61850 Smart grid protocol & software). Two numbers of 3 Phase Over voltage & under Voltage relay (110V/220V/415V) is to be provided for protection with PC Interface facility (IEC – Smart grid protocol). Relay Hardware should be uniquely designed hardware which replicates an actual relay. Multifunction meter (MFM384) with PC interface is required. Any algorithm can be coded and can be tested for its Characteristics and response. The Test Setup should be connected to a PC. Simulation data can be generated using simulation software and then can be downloaded to the Testing Software. The Test Setup then should generate the signals accordingly and passes to the Concept Relay Hardware. This enables students and research associates to verify and test different relaying / protection algorithms in a real life condition. Relay must be such that to allow interconnection with renewable sources and capable of reverse power flow control as well as metering.
