“…This testbed mainly consists of three IEDs, an ethernet switch, three personal computers, a GPS (Global Positioning System) clock receiver and time server, optical fiber cables, unshielded twisted pair (UTP) cables, as well as support software. This structure represents, on a small-scale, an IEC 61850 station bus [11]. In this scheme, IED 1 acts as a controlled GOOSE packet publisher, while IED 2 and 3 acts as subscribers from IED 1 messages.…”

There are numerous publicly available articles on digital substations, including those dedicated to current and voltage measurements, time synchronization, test systems development, principles of substation design, and other aspects of this topic. But the phase shift between instantaneous signals and the corresponding values in the SV (sampled values) stream has been little discussed. We can list the following principles to reduce the phase shift between instantaneous analogue and discrete signals and the corresponding values in the SV stream. 1) Exclusion from the device, of non-essential elements that introduce additional propagation delays of analogue and discrete signals, provided that such exclusion does not adversely affect the device performance or characteristics. 2) Reduction of the delay time for the other device elements to the minimum values. 3) Adjustment of the delay time of some device elements or addition of special delay elements to equalize the time of signal propagation over analogue and discrete channels. 4) Consideration of the total delay time of signal propagation over analogue and discrete channels and adjustment of the time stamp in the SV frame. The article provides examples of application of these principles in signal generation and measuring devices and phase shift meters.

“…One of the most driving components in the field of substation automation is the usability of the industrial Ethernet. Taking into account for the enormous progress reached in Ethernet technology over the years the decision was made to include it in the IEC61850 standard [3]. This paper describes the development of Bay Control Unit for substation automation.…”

This paper presents the development of Bay Control Unit for Power Transformer to build up substation automation system. The substation automation including digital control and monitoring of electric machine is widely spreading more and more, the degree of automation is more sophisticated and automation functions are required increasingly. These requirements of related power industries and customers can be satisfied by advanced digital IEDs such as digital protection relay, bay controller, PLC, communication devices, etc. By the fusion of state of the art technologies such as microprocessor, digital control, digital communication with conventional power industry, we can build a more effective, reliable, economic, convenient substation and power system. Nowadays, lots of power transformers are installed with a digital IED called Bay Control Unit. Bay Control Unit can simplify the conventional local control panel which is full of analog devices and lots of cables. It also make easy to install, test, maintain and any kind of change of power transformer and its control scheme. As long as the IEC61850 that is international communication protocol for substation automation is becoming popular, it is expected that digital IEDs will be used dominantly. We developed and are testing a Bay Control Unit, which can be specifed by IEC61850 communucation, flexible IO, module based structure, convenient control method. In this paper, we will describe modular structure, flexible IO and powerful flexible logic function combined with the dedicated PC application program. And we also explain the application and result. This technology can be also used in digital protection relay, RTU, PLC etc, so we expect it can improve the functionality, specification, and convenience of digital IEDs.
