The functions of line tripping detection (1 or 2 lines) as part of the MKPA-RZ complexes are certified

30 September 2020

The functions of line tripping detection (1 or 2 lines) as part of the MKPA-RZ complexes are certified by the System Operator of the Unified Power System.

Functions of emergancy control line tripping detection (1 or 2 lines) as part of microprocessor complexes MKPA-RZ produced by Prosoft-Systems have been tested in the system of voluntary certification of SO UPS, JSC.

Based on the test results, perpetual certificates were obtained confirming the compliance of MKPA-RZ IEDs that implement the function of line tripping detection with the requirements of the standard of SO UPS, JSC STO 59012820.29.020.008-2018 "Relay protection and automation. Automatic emergency control of power system modes. IEDs for line tripping detection and detection of the state of power transmission lines, power grid and generating equipment. Norms and requirements".

Previously, the MKPA and MKPA-RZ microprocessor-based emergency control systems manufactured by Prosoft-Systems have been certified for compliance with the requirements of SO UPS, JSC for IEDs executing the following functions: out-of-step protection, overfrequency protection, over-current thermal protection, under frequency protection. The functions of  out-of-step protection and overfrequency protection have also been certified as part of the MKPA-2 complex
