Introduction
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.
Benefits
- 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
Requirements
- 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
Solution
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.
Conclusion
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.

Exploración, desarrollo y producción
La industria de exploración, desarrollo y producción incluye actividades en altamar y terrestres, como la automatización de bocas de pozo, el fraccionamiento, la terminación y la separación para recuperar y preparar petróleo crudo y gas natural subterráneos o submarinos.
A medida que el petróleo es llevado a la superficie, debe ser separado antes de su transportación. Las etapas de separación primaria y secundaria distribuyen comúnmente el flujo de gas, el flujo de agua y el flujo de aceite en tres fases. El movimiento del gas requiere ductos y puede incluir un procedimiento de fraccionamiento en la etapa de exploración, desarrollo y producción antes de su desplazamiento. Los líquidos se pueden colocar en tanques o tuberías y ser enviados para su procesamiento, que requieren mediciones de nivel precisas.
