Network and Generator Connections
Network dynamics change significantly when previously asynchronous regions are connected via an AC interconnection. The connection of new generation sources also impact system dynamics. One of the major problems in extending an interconnection or adding new generation is the uncertainty surrounding the dynamic behaviour and interactions in the new configuration, when no previous operational experience is available.
Psymetrix's PhasorPoint solutions provide a fast and accurate means of measuring the actual dynamic performance across key areas of the power system in real-time. Using PhasorPoint it is now possible to deliver:
- Rapid assessment of the dynamic performance of the new synchronous region or generator
- An alternative to expensive invasive system tests (e.g. braking resistor tests)
- Evaluation of the robustness of dynamic performance over time
In some cases, dynamics problems have been noted months after an interconnection has been made, despite initial test results being satisfactory. In deploying PhasorPoint for continuous dynamics monitoring, an analyst can detect and investigate any conditions where unusual dynamics conditions occur and the causes tracked down before an event takes place that threatens network security.
In addition to providing PhasorPoint, Psymetrix can implement and manage entire programmes (including commissioning and upgrades) for:
- Regional interconnections
- Transmission lines
These programmes are flexible to suit customer needs, and range from advising utilities on the actions to be taken and assisting in the analysis of results, to operating the programme and even physical testing on behalf of the utility.
