Wide-area protection systems (WAPS) are becoming more popular among power systems around the world, due to their applications for employing remedial action schemes to avoid partial or total blackouts. Thus, this paper deals with building up a wide-area protection system simulator, conceiving its design and implementation in a simulated environment. A typical architecture of WAP is adopted taking into consideration that a wide-area monitoring system (WAMS) is in charge of measuring the frequency across the power system. The WAPS implementation is embedded into the DIgSILENT PowerFactory© and Matlab™ environments by making use of the Digsilent Programming Language (DPL) and Matlab scripts. Then, different remedial action schemes are proposed to avoid the unbalance in duo load and generation. The feasibility of the schemes is corroborated in different scenarios varying the disturbance that takes place in a benchmark version of the New England power grid. Finally, results exhibit and validate that the WAPS implementation and remedial action schemes in a simulated environment can be successfully addressed.
