A battery room is used to storage batteries for emergency power management in the plant. Each substation has battery room and the storage batteries are lead-acid batteries which must be maintained within specified operating temperature limits. Temperature management is important to ensure a long service life of the batteries especially for the plant in desert climates.
- Improved maintenance efficiency of storage batteries
- Minimized installation cost, a single hop up to 5km minimized wireless infrastructures (extra repeaters)
- Reduced system maintenance effort, battery life of 10 years with 30sec updates can be realized
- Improved system availability, the gateway redundancy with one second switch over time can be realized
- Improved future installation flexibility and usability, Backbone routers with Sky Mesh Method minimize infrastructure while maintaining high network reliability with low communication error rate
- To gather temperature and A/C measurements of each battery room and to monitor them in central control room
- All wireless transmitters to have redundant paths
- Host interface must be compatible with existing 3rd party DCS
- Minimize cost by reduced wireless infrastructure
Redundant gateways and access points were installed in a central control room. The wireless network has the availability to communicate with 24 battery rooms, over an area approximately 2 km2. In each battery room, an RTD sensor was installed for temperature monitoring and a mechanical flow switch was installed for A/C monitoring. Field and network redundancy ensured high availability of data. An OPC server with an open interface allowed for connecting to 3rd party DCS without any additional software.
Battery rooms are now under wireless monitoring. The redundant wireless system provides reliable network communication over 2 km2 area and cost savings were realized at over 75%. The emergency power monitoring system ensures that power is always available during a site safety event.

Yokogawa's innovative technology platforms and industry leading execution is well regarded in the global marketplace as a solutions partner pioneering the integration of technologies for all aspects of the oil & gas ecosystem from reservoir to enterprise. Proven solutions that include predicative business modeling, plant optimization and highly reliable automation platforms are assisting midstream operators to run their businesses at the optimal efficiencies. Yokogawa is helping clients to develop their automation roadmaps ensuring years of highly effective asset utilization and sustainability.
The upstream industry includes offshore and onshore activities including wellhead automation, fractionation, completion, and separation to recover and prepare underground or underwater crude oil and natural gas.
As petroleum is brought to the surface, it must be separated prior to transport. Primary and secondary separation stages commonly distribute gas flow, water flow, and oil flow in three phase separation. Gas movement requires pipeline and can include a fractionation process in the upstream stage prior to movement. Liquids can be placed into a tanks or pipelines and sent for processing, requiring accurate level measurements.
