AJ Power recently took part in a project authorized by an order from the Angolan President worth more than $240 million in total. The project consisted of the supply of seven hybrid power plants, fuelled by diesel and/or solar energy.
The contract to build and operate the power stations was awarded to a leading Chinese utility provider. As part of this project, the company chose AJ Power to build 12 of the generating sets required.
The solution provided by AJ Power consisted of 12 x 1000kVA prime power sets powered by MTU 16V2000G26F engines, fitted with Newage Stamford alternators.
All of the gensets needed to be synchronised together, with the ability to synchronise with mains in the future.
An InSight6000 control panel has been fitted to each genset which also synchronises with the photovoltaic cells and allows automatic adjustment of the output kW depending on the photovoltaic output, in order to keep the total kW power output stable for customer use.
The 12 generating sets were supplied fully installed in modified 20ft ISO type, CSC plated, sound attenuated containers complete with roof mounted residential silencers to achieve a sound level of 85dBA at 7 metres.
1000 litre baseframe fuel tanks with controls to allow refilling from a bulk fuel tank were also included in the design. A floor standing circuit breaker was installed at the rear of each container fitted with a power loom connected to the alternator terminals.
To enable ease of access for site power cable connections an opening below the circuit breaker in the container side wall was provided. The overall system design took into account the need for minimal set up time at site.
At short notice witness testing was conducted on two machines in AJ Power’s factory in Craigavon, in the presence of the end user’s Project Manager. The test included a demonstration of the full paralleling capabilities of the generating sets.
During his visit to AJ Power he also spent time on the factory floor with the operators installing the generator sets inside the containers and paid tribute to the people, products and response time.
AJ Power has successfully met the customers tight schedule. Indeed, despatch of the first 4 units was achieved within 4 working weeks from receipt of the order. The first batch of machines needed to be urgently on site, therefore 4 fully installed containerised gensets have been airfreighted to Angola via the very impressive Ukrainian Antonov AN-124 aircraft.
For 30 years, the Antonov AN-124 aeroplane was the world’s heaviest. It still remains the largest transport aircraft in the world. An unusual transport method for AJ Power generating sets!
AJ Power’s job did not end there, as the remaining 8 generating sets have been sea freighted within 10 working weeks from initial order.
