Digital protection relays are made to provide reliability, selectivity and speed to power system protection engineers. This paper focuses on local breaker failure protection, covering the basics and enhancements of BF detection.
The modern technologies utilized by microprocessor based protective relays provide the means to accelerate the extinction of the arc produced by short circuits where the air is the conducting material.
This white paper outlines the interoperability of IEC 61850. Our practices, with several use-cases for interoperability within a multi-vendor environment are analyzed. The architecture/process at the device level and system level is proposed too.
As the electrical network has evolved, substations have kept pace, bringing together technologies and strategies to improve the network, resulting in intelligent digital substations.
This paper will explore three key Smart Grid functions (Delivery Optimization, Demand Optimization and Asset Optimization) with the strongest business case justification.
This paper discusses how, in the electric power industry, Work Process Management can provide an environment to control, analyze, and audit activities across multiple departments.
This paper reviews the overall requirements for comprehensive windfarm protection. It also focuses on the problem of feeder ground faults and presents a solution making use of peer-to-peer messaging via the IEC 61850 protocol.
This paper looks at the specific application of PMUs for disturbance recording, with emphasis on wide area cross-triggering of recording PMUs during events.
