Cover Story

Standards Based Engineering of PAC Systems

The IEC 61850 international standard for substation and power system communications is not just defining a new protocol. It is also introducing abstract models of primary and secondary substation equipment, communications systems and the relationship between all of them. It also defines an XML based format for the description of the above in a standard way that can be used at different stages... More

IEC 61850 Update

TISSUES

TISSUES (Technical Issues) When you develop a standard that has multiple parts and more than 1000 pages, there is always a risk that inconsistencies are introduced between the different parts, or that what the Editor believes is pretty clear is interpreted differently by the developer. As a consequence, not only the standard needs to be fixed, but the developers also need to get an answer as ... More

Lessons Learned

Third Party Tools for IEC 61850 substation modernization projects

Vattenfall chaired the IEC 61850 working groups for adopting IEC 61850 to both hydro and wind power domains. During the last 8-10 years a number of internal R&D activities have studied the possibilities and benefits of applying IEC 61850 and internal guidelines have been developed in parallel to ongoing projects for applying the standard. The first IEC 61850 substations were commissioned i... More

Further there are additions to overcome problems experienced with Edition 1, and due to new functionality needed for other application areas. For backwards compatibility all additions are optional. Thus, if the new features shall be used, it should be checked if the envisioned Edition 2 IED has really implemented it. In practice the first actual usage of the SCL language at system level was ... More

PAC System Engineering Perspectives

PAC System Engineering Perspectives

This article considers a system that is first governed by never changing fundamental laws (Ohm’s Law), then by progressively evolved practices over time, all while surrounded by a series of standard that guide some of its realizations (e.g., IEC, IEEE, etc). Thus, though system engineering starts from a well-established basis, it needs a change supported by the evolving technology. This... More

Employee Personnel Files

In the previous issues we discussed some sensitive topics of employment related to employees’ privacy and more specifically the matter of employer searches and the different types of testing of employees at work. Although some of these measures are controversial, and may even look quite inapplicable, most of them are legal and are a widely accepted practice necessary for the betterment ... More

Device Independent Specification of a PAC System

Device Independent Specification of a PAC System

The migration towards renewable energies and smart grid technology requires innovation and investment. Utilities are under pressure to decrease costs without compromising the reliability of their services. It is proven that IEC 61850 helps to lower the hardware and wiring costs of an SAS. On the other side there have been high adoption costs for the new technology and whilst interoperability ... More

Protection History

The Development From 8 to 32 bit Microprocessors in Digital Relays In the last issues we covered the first digital relays and their predecessors. For digital relays in the 1980s 8-bit-microprocessors have been used. For the setup a serial interface on the front of the relay was used with setup-terminals in the first years and later with laptops (Figure1). Keypad terminals have also b... More

I Think

Platforms the way to a new world order

In the world of Smart Grids one of the major concerns is the return of investment or shareholder value. In the traditional way of thinking we take the costs, calculate the benefits and based on that define whether it makes sense to invest in a technology or solution. This model is based on the principle that money is scarce which was developed centuries ago. Recently newspaper articles have ... More
