relay-coordination 1.0.1

ETAP-style relay coordination simulation for pandapower

Relay Coordination Package

Professional ETAP-style protection coordination simulation library for Pandapower.

Features

• Relay Modeling: IEC 60255, IEEE C37, IEC 61363 curves
• Analysis: Short circuit (IEC 60909) and Coordination analysis
• Reporting: Automatic CSV generation and TCC plotting
• Easy API: Simple integration with pandapower networks

Installation

pip install relay_coordination

Or install from source:

git clone https://github.com/yourusername/relay_coordination.git
cd relay_coordination
pip install -e .

Quick Start

import pandapower as pp
import relay_coordination as rc

net = pp.create_empty_network()
# ... build network ...

# Add protection
ct = rc.add_ct(net, bus=0, primary_rating=200, secondary_rating=5)
relay = rc.add_relay(net, ct=ct, phase_pickup=100)

# Run analysis
rc.run_coordination_analysis(net)

# Plot TCC
rc.plot_tcc_curves([relay], filename="tcc.png", figsize=(12, 8))

Data Export

All analysis results and plots are automatically saved to the ./data/ directory by default.
