Overview of power system
DRAWBACK OF POWER SYSTEM WITHOUT SCADA
Human operators was required to monitor performance of each machine.
Power factor correction by human interference is not as precise.
Depending on human efficiency quality of work changes. Causes delay in finding problem, fault in a system.
Basics of SCADASystem
• Supervisory Control and Data Acquisition (SCADA) is a term used to describe the technology that enables a user to collect data from one or more distant facilities and send limited control instructions to those facilities.
• SCADA system consists mainly of the follows:1. Supervisory control and data acquisition.2. An industrial measurement and control system.3. Remote terminal unit(RTU).4. Master control unit(MTU).5. Communication system.
SCADA SYSTEM BASED ARCHITECTURE
Application of SCADA
Typically used by utilities such as power, Oil & Gas, water
and waste management, etc.
Processes that are spread over large geographical areas,
are relatively simple to control and monitor, and require
frequent, regular, or immediate intervention.
Industries where it is difficult for human to work.
CONCEPT OF PROJECT
It contains mainly three parts: Power factor Compensation technique . Correction technique using SCADA.
AC Power

Apparent power =
Power factor
P.F. = cos θ = P/S = R/ZPurely resistive load, R p.f. = 1
Inductive load, RL, p.f. <1 (lagging)
Capacitive load, RC, p.f. < 1 (leading)

CAPACITIVE
Power factor correction In this proposed project model, the reactive load used is
inductive
Therefore its power factor correction is achieved by the
addition of capacitors in parallel with the connected
inductive circuits,
or applied at the switchboard or distribution
panel.
The resulting capacitive current is leading
current and is used to cancel the lagging
inductive current flowing from the supply.

Conclusions
SCADA System with Automatic Power Improvement Unit can be used to improve the efficiency of the Power Utilities by improving: Reducing the power losses. Improving the power quality. Satisfying the continuous power need of all consumers. Hence benefiting the power utilities resulting into less
revenue losses.
