Reactive Power Compensation Technologies: State-of-the-Art Review

Invited Paper

This paper presents an overview of the state of the art in reactive

power compensation technologies. The principles of operation, design

characteristics and application examples of Var compensators

implemented with thyristors and self-commutated converters are

presented. Static Var generators are used to improve voltage regulation,

stability, and power factor in ac transmission and distribution

systems. Examples obtained from relevant applications describing

the use of reactive power compensators implemented with newstatic

Var technologies are also described.

Keywords—Reactive power, static Var compensators (SVCs).

 Reactive Power Overview and Importance to Bulk Power Systems

 

Reactive power (vars) is required to maintain

the voltage to deliver active power (watts)

through transmission lines. Motor loads and

other loads require reactive power to convert

the flow of electrons into useful work. When

there is not enough reactive power, the voltage

sags down and it is not possible to push the

power demanded by loads through the lines.

 

 In this Presentation we discuss the following:

• What is Reactive Power and where does

it come from?

• Why is it important?

• Reactive Power and Blackouts

• Reactive Power Delivery Limitations

• How Reactive Power Dispatch Has

Changed

• Advantages and Disadvantages of

Various Devices

Smart Grid

 

Smart Grid

Smartgrid is use of telecommunication to close the communication loop of generation and consumtion. Technical loss reduction,  distributed generation and renewable energy solutions constitute a major contribution of the smartgrid.

We perform system studies- load flow, transient simulation and contingency studies like transient stability of the network. Power electronics and embedded system design is our specialty.

We perform analysis, design and simulation of various communication protocols that are used for smartgrid. We work with FPGA, ARM, embedded Linux, multithreaded application, RTOS systems. We work with most board startup  linux  solutions.
