SCADA control is an industrial control system that is used in many modern industries such as energy, manufacturing, energy, water transport, etc. SCADA systems organise multiple technologies that allow you to process, collect and monitor data at the same time to send instructions to those points that transmit data. In today's world, almost anywhere can be observed SCADA systems, whether a sewage treatment plant, supermarkets, industries or even in your home. SCADA systems range from simple to large configurations. Most SCADA applications use human machine interface (HMI) software that allows users to interact with machines to control devices. HMI is connected to motors, valves and many more devices. The SCADA software receives the information of programmable logic controllers (PLCs) or remote terminal units (RTUs), which in turn receive their information from the sensors or entered values that we have manually given. SCADA in an energy system is used to collect, analyze and monitor data effectively, which will potentially reduce waste and improve the efficiency of the entire system by saving time and money.
As the energy system deals with the generation, transmission and distribution of energy sectors, monitoring is the main aspect in all these areas. Thus, the SCADA implementation of the power system improves the overall efficiency of the system to optimize, supervise and control the generation and transmission systems. The SCADA function in the power system network provides greater reliability and system stability for integrated network operation.
SCADA for power distribution system
The power distribution system deals with the transmission of electrical energy from the generation station to the loads with the use of transmission and distribution substations. Most energy distribution or utility companies rely on labor to perform distribution tasks such as disrupting power to loads, all parameters of time verification, fault diagnosis, etc. The SCADA implementation to The power distribution not only reduces manual operation and cost, but facilitates automatic operations without problems with minimizing interruptions.
SCADA for power distribution system
The figure shows the SCADA structure in the power system where it collects all information from several electrical substations (even in remote locations) and processes the corresponding data. The programmable logic controllers in the substations continuously monitor the substation components and the corresponding one transmits that to the centralized PC based SCADA system. In case of any power interruption this SCADA allows to detect the exact location of the fault thus without waiting for the calls of SCADA clients gives an alarm system to operators to identify and prevent. And also in SCADA substations, it automatically controls isolating switches and circuit-breakers for violating parameter limits, so that continuous inspection of parameters is done without a line worker. Some of the SCADA functions in the power distribution system are given below.
• Improve the efficiency of the power system by maintaining an acceptable range of power factor
• Limiting the maximum power demand
• Continuous monitoring and control of various electrical parameters under normal and abnormal conditions
• Trends and alarms to allow operators to address the problem
• Historian data and visualization from remote locations
• Fast response to customer service interruptions
