When a major petrochemical producer in Mpumalanga required an industrial UPS solution, the PowerLine DPA 20-120 kVA modular three-phase UPS system from ABB was selected. Many industrial sectors such as petrochemicals cannot afford any production downtime due to electrical power failure or disturbances. Not only does this require a complex and costly restart, but expensive end-product is ruined. Equipment may also be damaged in such instances, which also raises health and safety concerns.
Already a major supplier of electrical equipment and control gear to the petrochemical producer, this marks the first time that ABB South Africa has also been required to provide an industrial UPS solution. The PowerLine DPA from ABB is an online double conversion UPS that allows for the application of modular architecture in industrial environments that are typically very harsh on electronic equipment. It is based on ABB’s Decentralised Architecture (DPA) for benchmark UPS design in terms of availability, flexibility, cost, and ease-of-use.
Industrial plant environments pose specific design challenges such as high temperatures, dust, moisture, and corrosive contaminants. Therefore, the PowerLine DPA from ABB features a 15-year design life for maximum reliability and uptime. Each module has all the hardware and software necessary for autonomous operation, from rectifier to inverter, battery charger, static bypass switch, backfeed protection, control logic and HMI mimic display for control and monitoring.
The modular nature means that a single module’s output is unaffected by failures elsewhere in the UPS, as the load is simply taken up by the remaining modules.
Another major benefit is that the modules can be swapped out online, meaning they can be removed or inserted without having to power down or transfer to raw mains supply, which removes any risk to the critical load. This allows for continuous uptime and reduces mean time to repair (MTTR) failures significantly. Less spare parts must be held in inventory, which also simplifies system upgrades.
Modularity also relates directly to serviceability, as local personnel do not need specialised skills and spend less time on-site as a result, which helps to reduce the risk of any production loss. The PowerLine DPA at the petrochemical producer is expected to be commissioned in July this year.
