LECTURE 6: POWER SYSTEM AUTOMATION
Power System Automation is one of the important aspects in an electrical power network that needs
careful investigation. In power system automation, data acquisition system plays a major role as a
SUPERVISORY CONTROL AND DATA ACQUISITION (SCADA)
LECTURE 1: INTRODUCTION
SCADA is an acronym that stands for Supervisory Control and Data Acquisition. SCADA refers to a
system that collects data from various sensors at a factory, plant o
EMS LECTURE 1: INTRODUCTION
Electrical Energy Management System (EEMS) widely refers to a computer system which is
designed specifically for the automated control and monitoring of electric power and utility
system. The scope may span fro
EMS-LECTURE 7: Economic Dispatch and Optimal Power Flow
Economic Dispatch forms the important analysis functions dealing with Operation in an EMS.
Economic Dispatch (ED) is defined as the process of allocating generation levels to the
LECTURE 5: IEC61850 Standard for SCADA
5.1 Introduction to IEC 61850
IEC 61850 is a standard for the design of substation automation and a part of the International Electrotechnical Commissions (IEC) Technical Committee 57 (TC57) reference architecture fo
EMS-LECTURE 4: Network Analysis Functions
Network Analysis F (NAFs) are important functions that constitute the working of an EMS. The
network analysis functions are employed to determine, update the system state and use it for
Whether flying a small model rocket or
launching a giant cargo rocket to Mars, the
principles of how rockets work are exactly
the same. Understanding and applying these
principles means mission success.
In the early days of rocketry, th
EMS-LECTURE 6: POWER SYSTEM SECURITY
The growth of large interconnected power systems demands a high degree of security for normal
operation. The primary aim of an electric power system is to provide adequate uninterrupted
supply of electr
EMS-LECTURE 5: State Estimation
State estimator is an important tool for online monitoring, analysis and control of power systems.
State estimation is used in all Energy Management Systems (EMS) to identify the present
operating state of
LECTURE 3: SOFTWARE AND PROTOCOLS.
SCADA software is the most important aspect which runs on the hardware. Earlier SCADA was
mostly hardware and less on software. Presently, SCADA is 85% software and 15 % hardware.
SCADA software can be
LECTURE 2: SCADA HARDWARE
A SCADA system consists of a number of remote terminal units (RTUs) collecting field data and
sending that data back to a master station, via a communication system. The master station displays
the acquired data
EMS-LECTURE 2: WORKING OF EMS
Energy Management systems consists of several applications programs which are used by the
operator in a control centre for effective decision making in the operation and control of a power
system. These applicat
LECTURE 4: APPLICATIONS of SCADA
SCADA is widely used in different areas from chemical, gas, water, communications and power
systems. The list of applications of SCADA can be listed as follows.
Electric power generation, transmission
EMS-LECTURE 3: Operation States of a Power System
The operation of EMS is based on the working of the operating states. The power system
operates in two important areas, namely normal and abnormal states.
Operating States of a Power System:
What is adaptive optics?
Its a method of automatically keeping the light
focused when it gets out of focus.
If we observe light that is not in focus, we can
either move to a position where the light is in
