But we should always ask ourselves if what we are doing is the best we can do. Because what maybe was true yesterday may not be true today. Because the answer to the question should not be “This is how we always did it!” Let us think about what we need to do to implement a fairly simple protection scheme in the substation - for example, a breaker failure protection: 1.  We... More

Rail Energy Storage - grid scale energy storage

Renewable energy is one of the main tools that humanity has for fighting pollution and global warming. However, the widely used solar and wind distributed energy resources have a common problem - they belong to the category of variable resources with non-deterministic behavior which depends on the time of day, cloud coverage and wind speed. When these conditions are not favorable, we need to ... More

GOOSE Measurements

Within the substation or intercontinental ? How fast does the GOOSE fly?

In the early days of the use of communication protocols in power automation systems, this was only used for SCADA purposes. First of all, the media and protocols used in the past were comparably slow, their performance would have been insufficient for applications as those implemented with today's fast network technologies. And secondly, the reporting of e.g. a switch position to be displayed... More

Bus Protection ? A New and Reliable Approach

Why Bus Protection? Due to the critical nature of the bus component in the power system, a reliable method must be implemented to prevent bus faults from damaging equipment and disrupting system stability.  An internal bus fault without proper relay protection may cause rapid severe damage due to the high magnitude of currents involved and typically develop into a sustained loss of high ... More

Care for Employees - FMLA

The quality of our work product is a multidimensional event which is strictly dependent on the collaboration of many factors. If we put these factors on a scale, probably the amount and the quality of an employee’s education closely followed by the right amount of practical and theoretical experience, would be considered the first and most important one. Further, education without mo... More

Final Thoughts
At the beginning GOOSE was caged in the substation, intended to provide the high-speed peer-to-peer communications interface between protection, control and devices in distributed applications.  However, the many benefits that it provides make it difficult to keep it just there. We need to open our minds and start thinking out of the box. We need to think about what we can do better ba... More
