IEEE Std 1826:2020 REDLINE pdf download.IEEE Standard for Power Electronics Open System Interfaces in Zonal Electrical Distribution Systems Rated Above 100 kW.
IEEE Std 1826 identifies open system interfaces for high power electronics equipment used in zonal electrical distribution systems rated above 100 kW. Interfaces are grouped into key and non-key interfaces and are based on technological maturity, accepted practices, and allowances for future technology insertions. This standard defines how openness of system should be verified and validated through rigorous assessment mechanisms, interface control management, and proactive conformance testing to enable plug-and-play operability independently of the components origin. It also formulates specific interface requirements for open zonal electrical distribution systems on ships and platforms.
1.2 Purpose
The purpose of this document is to provide a uniform standard for high-power electronics open system interfaces in zonal electrical distribution systems rated above 100 kW. The stated specifications and requirements are universally applied to maintain total power system performance and efficiency under changing mission and loads conditions. They are will be sufficient for most industrial and (()mmercial installations, including ships and platforms. This standard complement IEEE Std 1662TM
1.3 Application and limitations
A zonal electrical distribution system (ZEDS) consists of power system elements serving a group of loads and is part of a larger power system. A—ZEDS plus the loads it serves comprise a zone.—A ZEDS has a limited number of power and control interfaces with the larger encompassing system and has the property that faults within the zone do not propagate outside the zonal boundaries.
This standard is intended to apply in cases where power electronics are the interface between the zones. It is not intended to apply whcw mechanical circuit breakers are the only means of is{)lating a zone. This standard applies to ZEDS employing power electronics and the loads served by the ZEDS aggregate to at least 100 kW. Possible applications include airports, hospitals, major data processing centers (especially those using uninterruptible power supply), broadcast systems, and maritime vessels and platforms.
Existing terrestrial power systems generally do not yet contain the electronic power interfaces and high-speed communication networks that are essential to use this standard. in some applications, ZEDS can be desied without the use of power electronics to achieve the ZEDS objectives. This standard does not apply to these applications; a long phase in period will thus exist bcforc this standard can be generally applied to these legacy systems.IEEE Std 1826 pdf download.
