September 2016 Issue
The idea behind focusing this issue of the PAC World magazine on the Grid of the Future and its impact on protection, automation and control systems is to look at the new realities and emerging technologies which have not been considered at the time when the electric power grid was built as we know it. If we think about the characteristics of the existing grid, we can summarize them under two... More

Cover Story

Protection Considerations for Interconnecting Solar Generation to the Transmission System

There is a significant amount of solar generation connected to the Georgia Power Company (GPC) distribution system. Solar generation that is directly connected to the transmission network, at 46kV and below is often mistaken for distribution connected generation. GPC-Distribution has developed a philosophy for interconnecting solar generation to the system that is different from the philosoph... More

IEC 61850 Update

Peer-to-peer communication in IEC 61850

It is a communication mechanism, where a publisher sends out information over the communication network and any device that needs the information can receive it as a subscriber.  From a communication interaction perspective, the publisher does not know, who is receiving the information. The subscription is implicit and defined through the engineering. Since multiple subscribers may ne... More

Lessons Learned

HVdc Transmission and Integration into an AC Grid

In the late 1990’s, power electronic technology that had been used for years in variable speed motor drives began being used in HVdc applications. Insulated-gate bipolar transistors (IGBT) were developed that had voltage ratings and current capabilities needed for HVdc applications. The first of these was put into service in 1997. HVdc converters utilizing this technology are referred t... More

Dynamic State

The solid state relays were short lived as early in the seventies, use of computers to mimic the operation of relays was timidly introduced. The introduction of the microprocessor based relay in the early 80s made the computer approach viable as a low cost but extremely powerful protection system. Numerical relays as we refer to any computer based relay, have the capability to implement the p... More

Simulation Based Testing and Measurements

These industrial sub-networks are capable of creating a stable island network. They are typically coupled to the grid of the distribution system operator (DSO) via one or two transformers. These transformers are built with high short circuit voltages (vsc) of 16-20% on purpose. This allows for a high damping during external faults. (Figure 1). Special industrial implementations even have mu... More
