SCADA Systems for Sub Station Monitoring:SubStation SCADA systems monitor data from various devices, including meters, inverters, breakers and substation equipment. These systems provide actionable information to determine whether substation is performing as expected and also identifying offline and malfunctioning devices. Operators and Engineers can analyze the SCADA data and determine if there are any issues.
Power distribution to various electrical loads at substations is controlled by switchgear feeders. Sensors mounted on the switchgear collect various data on current, voltage, power and switchgear status. This data is transferred to the RTU, which is in turn polled by a SCADA system.
The SCADA system consists of a master control station with one or more PC-based human machine interfaces (HMIs). The SCADA system may also contain other secondary control stations with HMIs, and large substations may also have local HMIs.
Substations are a critical component for maintaining electrical supply and load control in low voltage, medium voltage and high voltage electrical distribution networks. In order to ensure the proper functioning of substations and related equipment such as line-mounted switches and capacitors, most utilities use SCADA (supervisory control and data acquisition) systems to automate monitoring and control.
