3 Terms and definitions

The following terms and definitions apply to this document.

3.1 Setting calculation data

Used for relay protection fixed value calculation and equipment management, including regional plant (field) station parameters, primary equipment parameters, secondary equipment parameters, and operating methods Data such as formulas and graphics.

3.2 Principle-level setting calculation

For the relay protection settings that need to be coordinated in the power system, according to the setting calculation principle and the setting value coordination principle, calculate the protection function Electric quantity fixed value value.

Note: Generally, it includes the setting calculation of the phase-to-phase distance (impedance), grounding distance (impedance), zero sequence current and overcurrent in line and transformer protection.

3.3 Device-level setting calculation

For the relay protection settings that do not need to be coordinated in the power system, according to the setting calculation principle, calculate the electrical value of the protection function And the investment and return information, corresponding to generate a fixed value sheet that can be used for the protection device.

Note: Generally, it includes the starting fixed value, differential fixed value, control word, circuit breaker protection, reactor protection, overvoltage protection and other fixed values in line and transformer protection. Setting calculation.
