SUBSTATION TYPICAL SUBSTATION LAYOUT What is Substation? A substation is an important part of Electric power system. Substation performs many operations like voltage Step-up & Step-Down, measurement of electric quantities, controlling,…., etc.                              OR A substation is an assembly of many electric components connected in series or parallel at one specified distance for stepping up or stepping Down the electrical quantities and measurement and controlling of electric quantities. It may include power generation substation , Power transmission substation And power Distribution Substation . Main Components of Substation Ø Power transformer Ø Circuit breaker Ø Isolator Ø Lighting Arrestor Ø Relay Ø Capacitor bank Ø Earthing Ø Bus-Bar Ø Instrument Transformer Ø Conductors & insulators 1.     Power Transformer POWER TRANSFORMER “ Transformer is a static device which is used to step-up

Basics of Servo Motor and Its Types

Image
  A servo motor is a rotary actuator or a motor that allows for precise control in terms of the angular position, acceleration, and velocity. Basically, it has certain capabilities that a regular motor does not have. Consequently, it makes use of a regular motor and pairs it with a sensor for position feedback Block Diagram of Servo Motor Basics of Servo Motor A servo motor is a rotary actuator or a motor that allows for a precise control in terms of the angular position, acceleration, and velocity. Basically it has certain capabilities that a regular motor does not have. Consequently it makes use of a regular motor and pairs it with a sensor for position feedback.  The servomotor includes the motor that drives the load and a position detection component, such as an encoder. The servo system vary the controlled amount, such as position, speed, or torque, according to the set target value (command value) to precisely control the machine operation. Types of servo motor

SUBSTATION FAULT MONITORING AND CONTROLLING USING PLC AND HMI Introduction The idea of distribution Automation began in the 1970s. the motivation at that time was to use the evolving computer and communications technology to improve the operating performance of the distribution system. Distribution automation also provides many intangible benefits which should be given consideration while deciding for implementation of distribution automation. After the deregulation and restructuring issues are settled, distribution automation activities should increase. The economic growth and development of a country depend heavily on the reliability and quality of power supply. Generally, rigorous planning is done for the addition of the generation and expansion of the transmission network. However, the distribution system has generally grown in an unplanned manner resulting in highly technical and commercial losses in addition to poor quality of power. Block Diagram Substation aut
