SouthCoast Wind Project Faces Third Delay Amid Uncertainty

The SouthCoast Wind project, a major offshore wind initiative set to deliver clean energy to the New England grid, has encountered significant delays as contract negotiations stretch into their third extension. The project, located south of Martha’s Vineyard and Nantucket, has already been subjected to multiple setbacks, primarily due to shifting federal policies and increasing costs driven by inflation and supply chain disruptions. These hurdles have delayed the finalization of contracts and raised concerns about...

Utilizing Fault Resistance to Test Distance Relays

Taking power grid protection to an all-new level

BY JASON BUNEO & RENE AGUILAR, Megger

The testing of distance relays has evolved from testing simple electromechanical relays to the newest modern microprossesor relays. Most modern relays employ advanced algorithms that not only compare the direction of voltages and currents in the system but also rather look at other system components. For example, many modern relays utilize various methods in order to determine the direction of the fault such as negative sequence impedance, zero sequence impedance, cross polarization, and others. This is only one of the many parameters that make up the distance protection.

Due to this increase in complexity in distance relays, the test methods have also evolved from the simple traditional methods of injecting simple arbitrary test values to requiring more realistic test values. It is important to understand how these newer devices function in order to be...

Protective Relay Frustrations

Solving misoperation with line parameter measurements BY WILL KNAPEK, OMICRON USA Between 80 to 90 percent of all power system faults involve ground. Many protective relaying schemes depend on ground distance protection to accurately sense and locate ground faults on multi-terminal sub-transmission...

Why Net-Zero is Cheaper for the UK

The United Kingdom has set an ambitious target to achieve net-zero greenhouse gas emissions by 2050. This goal necessitates a comprehensive transformation of various sectors, including energy, transportation, and agriculture. While the environmental imperatives are clear, there is growing evidence...
