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 Operation

In recent years, there has been an exponential growth in the application of natural gas gensets sets for baseload electric power. The drivers of this growth can vary from tighter emission requirements and carbon reduction to green/sustainable financial incentives.

The numerous benefits associated with lean burn gas engines have encouraged users to consider applying gas genset packages into applications that have traditionally been limited to diesel packages.

These applications are Standby or Island Mode type applications. The term Island Mode refers to the use of a genset as a captive source of electrical power that is designed to operate independently of any national or local power distribution network. In practice, this type of operation may be applied in either one of two possible plant configurations.

1. Remote Generation

In the first scenario, the genset serves as the sole power source and has no connection with the mains supply. This is typically the kind of installation used in remote areas of a country that are therefore beyond the reach of any reticulated electricity network.

2. Mains Parallel

In this alternative scenario, one or more gensets may be connected in parallel with the electricity grid supply and will only operate in Island Mode when the mains supply is interrupted.

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:

Main Features (Shortened)

Wide Capacity Range: 6 kW–4000 kW, with options for parallel operation, grid connection, and power station setup.
Modular Design: Compact, lightweight, easy to install, minimal footprint.
Premium Components: International brand parts ensure reliability, safety, and stable performance.
Full Protection: Advanced electrical safety compliant with CE, IEC, and more.
Uninterrupted Supply: Large oil tank with auto-refueling for continuous power.
Rugged Performance: Special air/exhaust system and remote radiator for harsh environments.

Understanding the “Big Picture”

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 electrical distribution and
associated earthing system into which
the gas gensets are to be applied.

What are the allowable voltage and
frequency deviations and recovery
times?

What are the load details, for example,
what types of loads are being applied,
how many load steps are needed and
what is the load profile / strategy? It
may also be useful to understand if
there is any flexibility in the loading strategy.

Extraneous factors such as
environmental emissions limits,
altitude, ambient temperature,
available fuel type, gas pressure etc.

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.
