Expert Talk on High-Resolution Synchronized Measurements to Support Grid Resiliency and Asset Management
IEEE PES Vancouver Chapter is pleased to announce the following technical talk at BC Hydro Edmonds campus.
The theme of the talk is: “High-Resolution Synchronized Measurements to Support Grid Resiliency and Asset Management”.
Extreme weather conditions are demanding stronger grid resiliency. To help with grid hardening, event detection, and asset management, we have deployed wideband optical electric field sensors to enable a wide-area synchronized waveform measurement system on the transmission grids with up to one mega-samples-per-second (Msps) measurement resolution. This monitoring system helps in a variety of ways to improve the grid including:
1. Accurate event and fault location on the transmission lines, typically within 100 m, to assist with faster grid recovery (and shorter outage duration where applicable).
2. Help with asset investment prioritization based on identifying the weak areas of the grid; for example, identifying which few transmission towers are seeing most of the faults on a transmission line, so that key problem areas can be addressed (or replaced) on priority.
3. Incipient fault location on the transmission system to assist with corrective actions before the issues develop into faults and longer outages.
4. Post-event analysis, including performance of protection system during events.
This intelligent monitoring system helps improve grid resiliency; and most importantly, itself is architected to be very resilient and dependable. Practicality, safety, and cost efficiency have been core driving principles in deploying this system.
In addition to supporting travelling-wave-based accurate event location, the sensor system provides lower-resolution synchronized measurements such as 14.4 ksps (as recommended by IEC 61869-9) for digital substation and power quality and harmonics measurement, as well as continuous synchrophasor streaming ability at 60 or 120 measurements-per-second for wide-area grid performance and stability analysis.
In this presentation, we report on the measurement system performance and provide examples of field experience with accurate event location to support real-time grid operation, grid resiliency, and asset health management.
