Recent and Current Projects
WivGen is currently involved in various project around the world installing both new generation and distribution as well as upgrading older systems. Some of the project locations we are involved in are shown below.
Middle Eastern Manufacturing Client
Design of a multi-voltage capability system for a Middle Eastern Manufacturing Client with a remote monitoring system which allows WivGen to fix faults remotely.
A complex brief for a Middle Eastern Manufacturing Client – we delivered a system which could synchronise for soft transfer to the mains at three locations – two on low voltage and one on medium voltage. We designed a bespoke system including the specification of a transformer starter for a 1.5MW air compressor.
We helped the client save cost and create running efficiencies by installing a remote monitoring capability which meant the WivGen team could assist in solving faults quickly from anywhere in the world, saving time and cost.
PZ Cussons, Nigeria
We fixed a capacity problem for PZ Cussons in Nigeria, moving capacity which was down to 60 – 70% up to 90% with the introduction of diesel sets and one additional gas set to the existing gas system.
PZ Cussons in Nigeria had an issue with a gas generator grabbing the entire load and tripping, forcing the company to restrict generators to 60-70% of their maximum capacity.
This is a familiar problem with gas generators, to solve it we converted 10 diesel generator control systems to ComAp, modified the existing Cummins DMC 300 PLC and touch screens, and worked with another large gas generator installer to add an 8th gas set to the system.
The diesel and gas sets now work seamlessly as one generator plant, each automatically called by the DMC depending on load. As a result we able to run the system at a much more economical 80-90%, meaning cost savings for the client.
International Bank’s data centre
Design of generator control systems for 7 generators for a large International Bank’s data centre, making it safe, 100% reliable and simple to run and maintain.
We were commissioned by a contractor for a large International bank to design the generator control systems for 7 generators, which included mains and bus coupling controls, networking and head-end SCADA. We specified ComAp controllers on all the mains, and generators and bus ties were all linked together through a fiber network.
Dual redundant hot standby PLC’s monitor the entire control system acting as a watchdog to flag up and intervene where required. We kept the operation simple to run and maintain by specifying only one manufacturer system – ComAp.
