2MVA DIESEL GENERATOR INSTALLATION AT A GLOUCESTER GOVERNMENT TESTING FACILITY
INTRODUCTION
An incredibly bespoke and diverse diesel generator installation project for the WB Team, the specification contained a number of varied infrastructure requirements which WB were required to design and install. The finalised solution comprised one T2200, 2000kVA prime rated generating set installed in an acoustic container, along with an accompanying fuel management solution. The scope also included commissioning, testing and finally, training for the facilities engineering team. The proposed solution also came with a 12 month maintenance package, delivered by the WB Power Service department. This would ensure the generator was kept in full working order.
GENERATING SET
Following a detailed analysis of the hospitals power requirements, WB Power proposed the installation of a T2200, 2000kVA prime rated diesel generating set. The set was installed with additional bespoke work, which included:
- Low flow fan
- Engine and alternator heaters
- APM 403P Control panel
- Set mounted Schneider ACB with electronic trip
- Dual batteries and 20A CHA
- Lube oil make up system
FUEL MANAGEMENT SYSTEM
The designed fuel management solution designed and installed came complete with a 2,800 litre day tank, complete with 10m of mapress steel fuel pipework. This day tank was located within the acoustic enclosure, and was fed fuel by a 10,000 litre bulk tank, built to the following specification:
- Digital tank level indicator (4 – 20mA) to link to BMS
- Over/under bund alarm
- 2” over fill prevention valve
- Duty pump set and control panel
ACOUSTIC ENCLOSURE
The generating sets was installed in a bespoke acoustic container with penthouse inleet, which was designed to achieve a noise level of 75dBA @ 1m FFC. Further to this, the enclosure also housed a 2,800 litre day tank and an output connection panel. Finally, the enclosure was completed with:
- Fire valve
- Motor and gravity louvers
- Leak detection
- Lube oil make upfit out
- Load bank connection cat flap
EXHAUST SYSTEMS
The designed exhaust system comprised both a primary and secondary exhaust gas silencer system. The silencer was externally roof mounted in its own frame, made from stainless steel, and terminated in a horizontal tailpipe mitred at 45°. The exhaust system also contained a catalytic converter offering an up to 25% reduction in CO2 emissions.
COMMISSIONING & SITE TESTING
As part of the solution, WB Power provisioned for two Commissioning Engineers to be on-site for four days. The testing schedule included:
- G99 Test
- Site acceptance testing (SAT) including a resistive load bank test
- Fuel refill upon testing completion
- Injection testing
