A short brief on SCADA system in Power System. SCADA systems are used in power systems to monitor and control the generation, transmission, and distribution of electricity. They provide operators with real-time information about the state of the grid, which helps to improve reliability, efficiency, and safety. SCADA systems are essential for the operation of modern power grids, which are becoming increasingly complex and interconnected.

Welcome To My Presentation
Supervisory Control and DataAcquisition (SCADA)
System in Power System

2. Introduction to SCADA
System in Power System
Supervisory Control and DataAcquisition (SCADA) system is a computerized
control system used to monitor and control industrial processes, such as power
generation and distribution. In this section, we will discuss the components of
SCADAsystem.

3. The Components of SCADA System
1 RTUs
Remote Terminal Units are small,
rugged computers that collect and
transmit data to the central control
system.
2 PLCs
Programmable Logic Controllers are
computers with specialized operating
systems used to control machinery on
a factory floor.
3 Communication Networks
The communication network
connects all the components of the
SCADA system and makes the
transfer of information possible.
4 Central Control System
This system collects and analyzes the
data collected by the RTUs and
PLCs.

4. How SCADA System Works in Power System
1 Collect Data
RTUs collect data from sensors and other devices
throughout the power grid.
2
Transmit Data
The data collected by the RTUs is transmitted over the
communication network to the central control system.
3 Process Data
The central control system processesthe data and provides
operators with real-time insights into power system
operation.
4
Control System
Operators use the information provided by the SCADA
system to control the power system and keep it running
efficiently.

5. Benefits of SCADA System in Power System
Improved Reliability
Operators can quickly detect and respond to
power outages and other issues that could
affect reliability.
Increased Efficiency
Operators can identify ways to optimize
power generation, distribution, and
consumption to improve energy efficiency.
Cost Savings
By preventing power outages and other
issues, companies can save money on
repairs, infrastructure upgrades, and lost
revenue.

6. Challengesof SCADA System in Power System
Complexity
SCADA systems are complex and
require specialized knowledge to design,
build, and operate.
Security Risks
SCADA systems are vulnerable to cyber
attacks, which could have catastrophic
consequences for power systems.
Cost
SCADA systems can be expensive to
install and maintain, requiring significant
investments in hardware, software, and
personnel.

7. Conclusion
Despite the challenges, SCADA systems have become an essential component of
modern power systems. By providing real-time data and insights, SCADAsystems
help operators make better decisions and improve power system reliability,
efficiency, and cost-effectiveness.
