Abstract

Recognising the deep potential in wastewater treatment plant (WWTP) automation strategies, this research focuses on expanding the plant operations in order to optimally utilise the produced biogas during the wastewater treatment process to achieve electricity cogeneration and High Voltage/Low Voltage (HV/LV) redundancy. The research has resulted in a proposed design for a smart Remote Terminal Unit (RTU). The proposed design also enables a failsafe mechanism at different levels of the water treatment process and biogas production thus facilitating an automated WWTP electricity cogeneration. The proposed design also increases the life span of substations, reduces power demand load on the grids and enhances safety of WWTP equipment during various scenarios of electricity cogeneration, shut downs and maintenance operations. Monitoring, operating and controlling of WWTPs is a complex and challenging task. The power equipment in most of the existing or old WWTPs that generates electricity from the biogas produced in the water treatment process requires intensive supervision and control to enable failsafe and redundant electricity cogeneration process. This research focuses on setting up an effective communication system between power equipment at existing or older WWTP distribution substations and power company`s zone substations, without the need to upgrade expensive switchgear and power equipment in the network. The proposed philosophy achieves automated and failsafe communication network for SCADA link to enable WWTP electricity cogeneration, utilising exiting or old infrastructure. This critical multidirectional power and data flow requires proper compliant and semantic data models to guarantee smooth and safe operations. It also requires to be flexible and have the ability to develop and implement the telemetric mapping philosophy between the substations during various scenarios of electricity cogeneration and faults. This research has resulted in a proposal of smart Remote Terminal Units (RTUs) on existing or old infrastructure of WWTP to achieve electricity cogeneration with integrated renewable energy resource
