A Cost Effective Generator Brake For Improved Generator Transient Response

نویسنده

  • H. Jiang
چکیده

A cost effective, low maintenance generator brake is proposed using recent developments in thick film, metal oxide resistors. The brake has very low resistance, and virtually no inductance, allowing its use &ring a fault to slow a generator’s acceleration. Simulation results using the 39 Bus New England system show that placing brakes at each machine dramatically increases the global stability of a power system.

Finding the Minimum Distance from the National Electricity Grid for the Cost-Effective Use of Diesel Generator-Based Hybrid Renewable Systems in Iran

The electricity economy and its excessive consumption have become one of the main concerns of the Iranian government for many years. This issue, along with recent droughts, shows the need to use renewable energy that is free and clean and does not require water. In addition, due to the high cost of cable-laying and maintenance of power lines, it is not at all an option at all distances over the...

Sliding-Mode-based Improved Direct Active and Reactive Power Control of Doubly Fed Induction Generator under Unbalanced Grid Voltage Condition

This paper proposes an improved direct active and reactive power control (DPC) strategy for a grid-connected doubly fed induction generator (DFIG) based wind-turbine system under unbalanced grid voltage condition. The method produces required rotor voltage references based on the sliding mode control (SMC) approach in stationary reference frame, without the requirement of synchronous coordinate...

Improvement Performances of Active and Reactive Power Control Applied to DFIG for Variable Speed Wind Turbine Using Sliding Mode Control and FOC

This paper deals with the Active and Reactive Power control of double-fed induction generator (DFIG) for variable speed wind turbine. For controlling separately the active and the reactive power generated by a DFIG, field oriented control (FOC) and indirect sliding mode control (ISMC) are presented. These non linear controls are compared on the basis of topology, cost, efficiency. The main cont...
