MSBTE K Scheme – 315336 Power System Operation and Control Notes PDF
The MSBTE K
Scheme Power System Operation and Control subject is a core part of the Diploma
in Electrical Engineering curriculum. It deals with the generation,
transmission, distribution, and regulation of electrical power to ensure
that electricity supply is reliable, stable, and economical.
This subject
helps students understand how power systems are monitored, controlled, and
optimized under different load conditions. It combines electrical
machines, power electronics, control engineering, and computer-based monitoring
techniques.
Importance of Power System Operation and Control
- Ensures uninterrupted and stable supply of
electricity.
- Maintains frequency and voltage within safe
limits.
- Balances generation and demand in real time.
- Minimizes losses in transmission and
distribution.
- Prevents system instability, blackout, or
equipment failure.
- Improves efficiency and reliability of
electrical networks.
- Helps in integration of renewable energy sources
like solar and wind into the grid.
MSBTE K Scheme Syllabus Overview – Power System
Operation and Control
The subject is divided into
several units, covering power generation, load management, system stability,
and control mechanisms.
Unit 1: Introduction to Power System Operation
- Structure of power systems: generation,
transmission, and distribution.
- Functions of system operation and control.
- Load characteristics and variations: daily, weekly,
and seasonal load curves.
- Importance of load forecasting.
Unit 2: Economic Operation of Power Systems
- Concept of economic load dispatch (ELD).
- Input-output curves of power plants.
- Fuel cost minimization.
- Methods of economic scheduling.
- Introduction to optimal power flow.
Unit 3: Load Frequency Control
(LFC)
- Importance of frequency regulation.
- Automatic Generation Control (AGC).
- Primary and secondary load frequency control.
- Interconnected power system operation.
- Tie-line bias control.
Unit 4: Voltage Control and
Reactive Power Compensation
- Need for voltage regulation in power systems.
- Methods of voltage control: tap-changing
transformers, synchronous condensers, shunt capacitors, reactors.
- Role of FACTS (Flexible AC Transmission Systems)
devices.
- Reactive power balance for system stability.
Unit 5: Power System Stability and Security
- Types of stability: steady-state, transient,
dynamic.
- Power angle equation and equal area criterion.
- Security assessment and monitoring.
- Preventive and emergency control actions.
- Concept of blackout and restoration procedures.
Unit 6: Modern Trends in Power
System Operation and Control
- SCADA (Supervisory Control and Data Acquisition) in
power systems.
- Energy Management Systems (EMS).
- Smart grids and distributed generation.
- Role of Artificial Intelligence (AI) and Machine
Learning (ML) in load forecasting and system control.
- Integration of renewable energy resources.
Practical Applications of Power System Operation and
Control
- Load balancing between power plants in real
time.
