Analogue or Digital Generator Controls for Drilling Rigs and Ships
Britannia manufacture generator control panels using both analogue and digital technologies. Our generator control switchboards range from 600kW to 2500kW. Busbars can be constructed up to 6000A with100kA fault rating.
Our standard analogue control panel is based around the Ross Hill Controls AC control module, which has proven its reliability and ruggedness over 30 years as the industry standard for drilling rigs.
This control module was designed specifically for systems where electric drives introduce distortion on to the generator bus. It is a complete control and instrumentation solution in a compact package which is easily maintained or replaced in the unlikely event of failure.
The module incorporates:
Our digital solution is based on the Woodward 2301D digital load sharinga and speed control package, and the Basler DECS-200 Digital Excitation Control System.
The 2301D provides control in either isochronous, droop, or base load. The 2301D will allow for soft load transfer when being added to or removed from a bus. In addition it has the following features:
The DECS-200 Digital Excitation Control System can accommodate 32Vdc, 63Vdc, or 125Vdc applications up to 15Adc. This unique flexibility provides precision control of generators of virtually any size. The DECS-200 also incorporates a pulse width modulated power stage, which improves system performances in non-linear load applications.
