SAMPLE PROJECT
PEA Thailand

Steps to Build an ANM System

Project setup will depend on the type of network management and available data

Class 1

  • Scheme is based on a pre-populated template to reduce configuration work

  • Manage real-time power flows (or voltages) at a monitored constraint locations

  • Control active power (MW), reactive power (MVAr)  or voltage

  • Limited number of constraints depending on the network size

  • Monitor real time power flows (or voltages) at up to 20 circuit breakers

  • Issue setpoints to a maximum of 10 generators/demands

  • Specify ratings in MW, MVA or amps for 20 circuit breakers and 10 transformers

Class 3

Includes all Class 2 features, plus:

  • Manage multiple constraint locations

  • Cost based LIFO stack

  • Pre-Fault rating calculations

  • Geographical network view

  • Requires a full network model and geographical data

Class 2

Includes all Class 1 features, plus: 

  • Required topological network model to allow for a switched network topology

  • Circuit and transformer ratings can be switched based on the circuit breaker states in order to represent N-1 running arrangements and ratings

  • Generator sensitivity checks performed to ensure only contributing generators are curtailed

Class 4

Includes all Class 3 features, plus: 

  • Full AC load flow

  • Manage links to Class 1 or Class 2 systems

  • Requires Class 1 and 2 scheme details
