SCADA (supervisory control and data acquisition)

SCADA

SCADA is one of many tools that can be used while working in an environment where operational duties need to be monitored through electronic communication instead of locally. For example, an operator can position a valve to open or close through SCADA without leaving the control station or the computer. The SCADA system also can switch a pump or motor on or off and has the capability of putting motors on a "Hand" operating status, Off, or Automatic. "Hand" refers to operating the equipment locally, while Automatic has the equipment operate according to set points the operator provides on a computer that can communicate with the equipment through SCADA.

SCADA gives PLC automation the brains to interact with switching-monitoring-control-email fault reporting-and anything else you can dream up or throw at it for automation control. More code writing and programing is required but well worth the time spent with professional engineers, programmers and a host of others for trouble free system automation of any project.

But also SCADA can be self taught with a whole lot of reading and prototypes, sampling and research and development by someone wanting to tone it down but still having the ability to add new items when they become available on today's market or system updates.




Combining certain dc to ac inverters in stacked and racked bundles for increased ac amperage output in parallel connection, automation is necessary to control both dc voltage/amperage and ac voltage/amperage. By having ATS (automatic transfer switch) up to 1,600 amp matched to SCADA PLC many options are available. These connections are island style where they can monitor grid, generator, battery bank inverter power or any other power source and automatically switch back and forth as programed with SCADA PLC automation. These island style power transfers are so fast that clock/computer resets are not needed

There are large scale projects in operation in the USA and elsewhere that are using this same principle to make MV (1 MV=100,000/volts) from lithium ion battery banking. During off peak hours the charging cycles are doing there thing. During peak hours the dc battery banks are brought online for cycle operation. These systems do not have solar or wind charging they are using the grid as a battery charger and storing off peak hours into dc banks to cycle over and over as described.




As for your secondary voltage/load any secondary voltage can have switchable transformers that are designed for solar/wind applications to step up the voltage to 7.2  KV primary ac voltage island style connected using SCADA PLC automation to make mini microgrids possible anywhere.


Your own mini microgrid for free electrical power is very easy by combining these different off the shelf products that are all controlled by SCADA PLC automation to make voltage/amperage matched to the clients needs possible anywhere on grid or off grid.

Homes cabins, ranches, farms, crop watering, agriculture, telecom, remote off grid, villages free electrical power is an investment of quality products matched to clients requirements for clean, safe, reliable, electrical power 7/24/365.
