Project description 

his project required the design and installation of a complete SCADA system and automated downstream level control on fourteen new open canal headgates. There was no existing infrastructure in place for this project.

Main project points:

  • Office SCADA server, radio communications system and related IT were installed. Inductive automation Ignition was utilized as the Human Machine Interface (HMI). Appropriate IT security was provided to allow for secure remote access for system management and alarms. The SCADA development includes provisions for future migration of the Districts old SCADA system to this platform.
  • All remote gate and downstream level sites had no power available. In addition, the system was required to operate year round 24-7. Therefore; low winter irradiance levels were used to design the required solar power and battery storage. A complete MPPT solar management data system was included as part of SCADA information development.
  • The canal level measurement points were in some cases one mile downstream from the headgates. This required the development of custom control algorithms that could achieve level targets within required control limits.
  • Level measurement site were designed as separate solar stations installed downstream on canals. Level data was sent back to the head-gate Remote Terminal Unit (RTU) using an autonomous radio links.
  • Custom RTU and Remote level site vandalism enclosures were developed to be modular and could be preconfigured for rapid deployment as gate sites were installed. See installed RTU and Level vandalism enclosures.
