The article provides a library for modeling relay protection in a Simulink environment.
The library (ver. 1.0.1 of 03/10/2019) contains the following elements:
- Maximum and minimum relay
- Impedance Relay (Mho)
- Power direction relay
- Biased Differential relay
- Time delay
- Trip delay
- Reset delay
- Pulse delay
- Inverse time delay
- Logical elements (AND, OR, NOT elements)
- Fourier filter
- RMS Filter
- Filter of Symmetrical Components
- Filter of Emergency Components
- Additional blocks
- RS flip-flop
- Filter of Maximum / Minimum value
The library for modeling relay protection is given in the following file: relay_library.mdl
The library will be constantly updated, stay tuned.
