The specialist engineers at Rudds can provide embedded generator services including design, generation of protection relay software, factory and site acceptance testing of embedded generator protection schemes. Rudds also provides negotiation and coordination with ActewAGL.
These projects were undertaking to enable the connection of class 2 to class 5 embedded generator systems to the ActewAGL and other electricity networks. Embedded generators have been diesel or gas fired reciprocating engines and PV or gas turbine powered grid connected inverters.
Key Services Components
The following key services components were undertaken by Rudds in the projects identified above.
- Protection system design
- Protection relay logic and settings
- Coordination with network service providers
- Factory testing
- Site testing
Rudds Consulting Engineers is pleased to offer the electrical industry a one-stop shop for Embedded Generation Protection.
We have led the way, together with utility partners ActewAGL to develop secondary protection systems for photovoltaic generators suitable for grid code compliance, and have extensive experience in the programming, Factory Acceptance Testing (FAT) and commissioning of utility mandated Photovoltaic Generator Connection Cubicles (PVGCC).
As a pioneer in the development of the first PVGCC together with ActewAGL, Rudds has intimate knowledge of the protection relays, and has been called upon for programming and FAT of most PVGCC units installed to date, and has completed the commissioning of all current PVGCC units to ActewAGL requirements.
Rudds has also designed, tested and commissioned similar protection systems for embedded generation systems such as tri-generation, Diesel Rotary Uninterruptable Power Supplies (DRUPS) and standby generators with no-break return to grid functionality throughout the Australia.
Rudds offers the industry:
- Technical advice on the current PVGCC as documented for ActewAGL
- Programming, FAT, and commissioning of PVGCC units built to ActewAGL standard specifications.
- Customised protection solutions for embedded generators to meet local utility and site requirements. This includes solutions for:
- Embedded tri-generation systems.
- Photovoltaic systems.
- Standby generators with no-break return to grid classified as embedded generators by the utility.
- DRUPS connected with potential to parallel with the grid.
- Expertise in the use, programing, testing and commissioning of utility grade protection relays like the P142 and P143.
