dotTC57

dotTC57 is a pure .NET implementation of IEC Technical Committee (TC) 57 standards for power systems management and information exchange. This library provides a comprehensive set of C# models representing the IEC 61970 and IEC 61968 Common Information Model (CIM).

Overview

This library focuses on providing:

1. A complete and well-documented object model representing the IEC TC57 electrical standards
2. Fully-typed C# classes with XML documentation
3. Models suitable for integration into power system applications

The core models are derived from the UML model available at the CIM User Group. The original EAP files from that site can be viewed with Sparx Enterprise Architect.

Model Structure

The library contains models organized according to the IEC standards structure:

IEC61970 Models

• Base: Core power system resource models, measurements, and domain types
• Dynamics: Dynamic behavior models including:
  • Excitation systems
  • Power system stabilizers
  • Turbine-governors
  • Synchronous and asynchronous machine dynamics
• Generation: Generation models
• Topology: Network topology models
• Wires: Transmission and distribution equipment models

IEC61968 Models

• AssetInfo: Information about physical assets including:
  • Equipment standards (ASTM, DIN, IEC, IEEE, ISO, TAPPI)
  • Cable and wire specifications
  • Power transformer specifications
• Assets: Asset models and asset containers
• Common: Common components shared across the model
• Customers: Customer models and agreements
• Metering: Metering components and readings
• Operations: Operational models
• Work: Work management and scheduling

Usage

These models can be used as the foundation for:

// Create power system components var transformer = new PowerTransformer { mRID = Guid.NewGuid().ToString(), name = "Transformer 1", description = "Main power transformer" }; // Link components together var terminal = new Terminal { mRID = Guid.NewGuid().ToString(), name = "Terminal 1", ConductingEquipment = transformer }; // Add specifications var transformerInfo = new PowerTransformerInfo { mRID = Guid.NewGuid().ToString(), name = "100MVA Transformer Spec" };

Documentation

The library includes comprehensive XML documentation that can be used to generate API documentation using standard .NET documentation tools like DocFX:

# Install DocFX dotnet tool install -g docfx # Create documentation project mkdir -p docs cd docs docfx init # Configure docfx.json to point to your project # Build documentation docfx metadata docfx build docfx serve _site

Model Implementation Details

• Complete Implementation: All classes from the IEC 61970 and IEC 61968 standards are included
• Strongly Typed: Native .NET types used throughout (string, double, int, etc.)
• Well Documented: XML documentation comments on all classes, properties, and enumerations
• Namespace Organization: Clear namespace hierarchy matching the IEC standard structure

Future Development

These models provide the foundation for:

• Integration with data persistence layers
• Power system analysis applications
• RDF/semantic web implementations
• Import/export to industry standard formats
