Document Description
The Phasor Measurement Unit-TEAM system will provide real time alarms for phase angle limits and enable Transmission System Operators to detect and address voltage instability as well as assist the Transmission Planning & Engineering sections to validate and calibrate dynamic models and run transient system stability analysis. Implementing this project will allow for immediate accessible data collection. TEAM software will also allow for continuous background monitoring and reporting. Project will be located throughout IID's service territory. The project will include engineering services by Schweitzer Engineering Labs and equipment installation by IID personnel at fourteen different sites. The installation of this equipment will provide phasor measurement information to Transmission Planning & Engineering for NERC requirement MOD-33-1 steady state and dynamic model validation. On July 1, 2017, the new NERC reliability standard MOD-033 became effective with the purpose of validating system models during steady state and dynamic operations. While steady state conditions can be validated with historical data that originated as SCADA data (1 measurement every 2-6 seconds), the dynamics of system models are validated against high frequency data (30 measurements/sec or higher). The acquisition of this high frequency data is necessary to maintain compliance with this new standard. The standard requires periodical model validation, which stresses the collection of all possible PMU data. This will allow for the gathering of fault data remotely from the engineering support groups.
