Background
In 2011, Sunwater were looking to replace and update a dated SquareD PLC Control System and custom built HMI with a new model PLC and SCADA system to control and monitor the Leslie Dam Spillway Gates. As well as Control System hardware and Software, the tender also called for replacement of customised control panel displays and instrumentation.
The Challenge
- Hardware Design and Manufacture
- Conversion of Square D PLC code and re-write to Sunwater standards
- Develop SCADA standards and implement
- Complete project management documentation to rigid standards
The Solution
Downey Engineering was awarded the contract and utilised their skills in design to come up with a solution that not only fitted with the current dam operation but improved its reliability. Off the shelf components replaced customised electronics and design was updated to improve redundancy.
The Result
The project was delivered on time and on budget with full site changeover and testing completed within the allocated window. Exhaustive in-house and FAT testing delivered confidence in the site commissioning process and Sunwater were delighted with the results.
