Use of XML for the data semantic of DER Object Models

DRAFT 2003-09-05 (has been automatically created from a XML file through a transformation)

These examples are intended:

• a single XML document (Data_Semantic.xml) contains the complete definition of the data semantics
  
• the transformation (Data_Semantic_VIEW.htm) automatically creates a table from the XML document
  
• the transformation automatically creates hyper links for easier navigation
  
• the transformation automatically creates anchors for easier navigation by other html pages
  

Benefit: DEFINE THE DATA SEMANTIC ONCE IN XML -- USE THEM MANY TIMES for different views!!!

Brief tables of LN classes defined in IDER Oblect Models

(Tables provide just DATA Class Name and Explanation)

LN: DRCT   Name: DER Controller

The DER Controller Logical Node defines the characteristics of the environment of the DER device, and its connection into the local and (optionally) the utility Electric Power System (EPS).

LN: DRGN   Name: Generator

The following Logical Node defines the DER generator characteristics. Each DER unit has a generator. Although each type of DER provides different prime movers for its generator, thus requiring different prime mover logical nodes, the general operational characteristics of these generators are the same across all DER types. Therefore, only one UCA DER generator model is required.

LN: DSYN   Name: DER Synchronizer

The GSYN logical node compares various voltages to ascertain whether or not they are synchronized with each other. When a synchronous condition exists between the compared voltages, closing of the generator breaker is permitted.

LN: DCOV   Name: DER Converter/Inverter

DCOV defines the characteristics of the converter and/or inverter, which converts the generator output voltage and/or frequency to levels compatible with the local or utility grid. The different prime mover LNs and the MMSU LN handle the actual measurements of converter inputs and outputs.

LN: DIES   Name: Diesel Engine

The diesel engine characteristics covered in the DIES logical node reflect those required for remote monitoring of critical diesel engine functions and states. The DIES LN attributes contain strictly non-electrical objects, even though typically a diesel genset consists of a combined diesel engine and generator.

LN: DFCL   Name: Fuel Cell

The fuel cell characteristics covered in the DFCL logical node reflect those required for remote monitoring of critical functions and states of the fuel cell itself.

LN: DPHV   Name: Photovoltaics System Characteristics

The photovoltaics system characteristics covered in the DPHV logical node reflect those required for remote monitoring of critical photovoltaic functions and states.

LN: FUEL   Name: Fuel Systems

The fuel system characteristics covered in the FUEL logical node reflect those required for remote monitoring and control of critical fuel system functions and states. These may vary significantly based on the type of DER.

LN: BATT   Name: Battery Systems

The battery system characteristics covered in the BATT logical node reflect those required for remote monitoring and control of critical auxiliary battery system functions and states. These may vary significantly based on the type of DER.

LN: ENVR   Name: Environmental Conditions

The characteristics of the environment of the DER system cover meteorological and other key environmental parameters. In addition, many of the environmental sensors may be located remotely from the instantiated logical node. This logical node may therefore represent a collection of environmental information from many sources. The need for different objects may vary significantly based on the type of DER.
