MTU gensets ready for German grid connection

Rolls-Royce Power Systems

Rolls-Royce Power Systems subsidiary MTU Onsite Energy’s Series 4000 gas generator sets have been certified as compliant with German guidelines for grid connection, the company has announced.

Moeller Operating Engineering, the certifying body, awarded the certification to MTU’s gensets with power outputs from 750 kW to 2600 kW.

The medium-voltage directive issued by Germany’s Federal Association of the Energy and Water Industry (BDEW) outlines the technical requirements necessary for connection to the nation’s grid. With the certification, MTU’s gensets are now authorised to feed power into the grid.

To satisfy the technical requirements set out in the latest revision of BDEW’s Technical Guideline for Generating Plants Connected to the Medium-voltage Grid, MTU said extensive modifications were needed to the design of the gensets as well as to their protection and control technology.

‘Being armed with this certificate puts us in a very strong position on the market for gas gensets,’ said Jàƒ¶rg Mielke, MTU’s head of sales in Germany.

DBR to deliver custom gas genset for GDF Suez platform

GDF Suez

Netherlands-based genset manufacturer DBR Generatorsets has announced that it is on schedule to complete construction of a custom-engineered gas engine-driven generator set by the end of 2014.

The 275 kVA generator set is to be delivered to oil and gas firm GDF Suez E&P Nederland BV for installation on its E17a-A offshore platform. According to DBR sales manager Henri Hafkamp, the genset is being custom fabricated due to space restrictions on the platform, with the air cooling unit outside the engine room and heavy components reduced to a minimum.

In addition, DBR said it is engineering the genset within a single frame instead of the usual double frame, again due to space limitations. As a result, the construction uses more robust components in order to reduce the risk of vibration.

DBR chose a MAN E2842 E312 lambda 1 engine, which it says has an optimum oxygen to gas ratio, and a Leroy Somer air-to-air cooled generator. The genset will be able to operate for up to 1200 hours between maintenance intervals, DBR said, adding that future maintenance will be an efficient procedure due to its stainless steel flanged joints.


Rental gensets to power South African mining operation


South African mining operation

South African firm Mineral Commodities Ltd (MRC) is to develop and operate its Tormin mineral sands mine project using a fleet of rental gensets for prime power.

Genset distributor Barloworld Power supplied the firm with three Cat C15 gensets, two Olympian GEP220 gensets and three Olympian GEP165 gensets, all prime rated. The three Cat C15 units and one of the Olympian GEP220 units are to provide power to the main processing plant, while one of the Olympian GEP165 gensets is to be used as pilot power when needed. The rest of the units will power mobile processing plants.

‘While the mine initially sought to purchase two generator sets, we offered a ROP (rental with an option to purchase) agreement that enabled MRC to acquire a comprehensive suite of eight generators within budget,’ said John Stander, fleet health manager at Barloworld Power Rental.

In the ROP option, as opposed to normal rental or outright purchase, the customer rents the equipment, and after 12 months has the option to purchase the solution at a significantly reduced cost.

‘This option was chosen for Tormin as it allowed MRC to avoid the initial capital outlay associated with outright purchase,’ said Stander. ‘This is particularly important during the development phase of a project, where costs are already high, as it enables the customer to install essential equipment while deferring purchase until the operation is generating income.’

Cummins Generator Technologies announces grid code-ready alternator range

Cummins Generator Technologies

Cummins Generator Technologies today announced the availability of their range of ‘Grid Code Ready’ STAMFORD and AvK alternators.

The new line of alternators has been engineered to meet global Grid Code regulations ahead of the German certification deadline and ENTSO-e certification implementation, Cummins said.

Ranging between 4000 and 18,000 kVA, the Grid Code Ready alternators are designed to assist genset manufacturers in meeting the impending global Grid Code legislation rollout, beginning in Germany on 1 January 2015 and progressing to the rest of Europe and the world thereafter.

Cummins says it will guide customers to compliance with dedicated customer support teams specialising in Grid Code technologies. The company added that, to assist with compliance, customers will also have exclusive access to a certification modelling tool which can be used with any prime mover when used in conjunction with real-time practical data.


Reissued Cat gensets used in Algerian desert drilling


Algerian desert drilling

Germany-based Cat dealer Zeppelin Power Systems has delivered a fleet of customised Cat gensets for use in an oil drilling operation in the Algerian desert.

Drilling rig manufacturer Bentec GmbH needed to power four rigs in harsh environmental conditions and high temperatures. The customer wanted to use Cat 3512A gensets, a power rating no longer in production, as well as requiring a special frame to fit in their containers. Zeppelin’s workshop in Achim, Germany worked with Caterpillar and its Lafayette Engine Center in the US to reissue and configure the 3512A gensets, delivering 16 gensets – four per drilling rig – each equipped with mechanically driven Cat 3512A engines plus a generator, cooler and frame. Each unit was also equipped with a Cat C15 genset for emergency power. Each engine delivers 1500 kVA at 600 V/60 Hz and the overall power output is 24 MW, or 6 MW per drilling rig.

To meet the demands of the harsh desert environment, Zeppelin developed a matching double-filter system, allowing for a quick change during running operation. Additionally, air and oil filters can be replaced without interrupting the power supply and stopping the production.
