- Case Studies
The threat of power shortages caused by the closure of major power stations and a reliance on renewable energy to compensate for this demand could potentially put at risk your security of power supply.
Gas powered generation plants, which can be operated continuously, or through standby application, offer a reliable and cost-effective solution to meet this electricity demand.
Should the site experience a loss of power, MWM gas engines can be configured to function in Island Mode and Black Start Operation.
Island Mode introduces a number of challenges for gas gensets, so a scheme incorporating gas engines needs careful planning and the following will need to be considered:
A gas engine will have less load pickup (transient) capability than a diesel engine, both in terms of how large a load step the engine can accept and how large the voltage / frequency deviation will be. Also, the recovery time after a load step is longer for a gas engine. Consequently, it is important to understand the application and to manage expectations.
Generally, as engine fuel efficiencies have increased and emissions levels have reduced, gas engines’ capability to accept step loads has decreased. To combat this, engine variations have been introduced with improved or optimised transient capability. The key to a successful Island Mode application is correctly sizing the engine so that it is matched to the application’s needs.
The only way to ensure a successful Island Mode application is to understand the user’s bespoke and unique requirements. The “Big Picture” is derived from the details. There are lot of different factors, each of which are important, that affect Island Mode performance. It is therefore imperative that all these factors are understood, for a successful Island Mode application.
Factors to be considered are:
The MWM TCG range of gas engines are relatively straightforward to configure for Island Mode Operation. Should Island Mode be considered, it is vital to engage with an experienced solutions provider, such as Edina.
We have a dedicated multi-disciplinary team whose collective in-depth knowledge and expertise in this arena, has made us a leading authority on all aspects of the applications of both gas and diesel gensets for Island Mode Operation applications.
