An Efficient Speed Controller of Three Phase Induction Motors Through Direct Torque Control - 01/0

Madbouly, S. O, Soliman, H .F

01/04/2016

for three phase (3-ph) induction motors based on direct torque control (DTC). The main function of the DTC is to control the flux, developed torque and the direction of rotation. Many industrial applications require a precise speed control. Most of the available controller techniques could not grantee keeping the 3-Ph induction motor speed constant, while subjected to mechanical load disturbances. A high rejection of the effect of mechanical disturbance is achieved through using the proposed technique with an excellent motor speed regulation as shown in the simulation results. Different speed trajectories have been carried out to verify the robustness of the controller. A variable gain PI controller is introduced to cover all speed references and provide to be an efficient controller. Keywords— Speed Control; 3-Ph Induction Motors; Direct Torque Control; and Variable Gain.

Advanced modeling and analysis of the loading capability limits of doubly-fed induction generators - 01/0

Mohamed Abdelreheim Mohamed Badr

01/01/2014

This paper presents an improved mathematical model required for evaluation of the steady-state power characteristics and loading capability limits of doubly-fed induction generators (DFIGs). Unlike the previous models, this model takes into consideration the effect of the losses, rotor power flow, and power factor settings of the grid-side converter (GSC). The impact of various variables and parameters on the loading capability is determined through detailed analysis of the loading capability limits as well as a parametric analysis. Simulation results show that DFIGs can provide a continuous controllable reactive power support to electrical grids. In addition, the results set rules for enhancing the reactive power capability of DFIGs based on its sensitivity to various parameters and variables of the machine and its controls. Although, squirrel-cage induction-generators (SCIGs) that connected directly to the grid do not have a reactive power capability and their reactive power consumption is uncontrollable, its loading characteristics are also presented for illustrating the value of the partial-scale converter in operational flexibility enhancement in DFIGs based systems.

A Microturbine Interface System with LVRT Capability - 01/0

Mohamed Abdelreheim Mohamed Badr

01/01/2014

Microturbine Units (MTU) are used widely as distributed generators for their proved advantages. This paper presents an interface system for the Microturbine Unit (MTU) based on back-to-back converter to operate in grid connected and islanding modes. Besides regulating the active power fed from the MTU, during the grid-connected mode, the proposed interface system regulates the Point of Common Coupling (PCC) voltage at its rated value. Moreover, the proposed interface system is controlled to have a Low Voltage Ride-Through (LVRT) capability by feeding the grid with reactive power during grid faults. Furthermore, the proposed interface system keeps the voltage and frequency at the load terminal during the islanding mode of operation with the same control structure. Simulation results are provided to evaluate the dynamic performance of the proposed MTU interface system at the different modes of operation.

Coupling of Wind Farms with Nuclear Power Plants - 01/0

Mohamed Abdelreheim Mohamed Badr

01/01/2013

Countries in the Arab region are planning to meet their increasing electricity demands by increasing both nuclear and Renewable Energy (RE) contributions in electricity generation. In the planning phase of siting both new Wind Farms (WFs) and Nuclear Power Plants (NPPs), many benefits and challenges exist. An important aspect taken into consideration during the NPP siting is the existence of ultimate heat sink which is sea water in most cases. That is why most NPPs are sited on sea coasts. On the other hand, during WF siting, the main influential aspect is the existence of good wind resources. Many coastal areas around the world fulfill this requirement for WF siting. Coupling both NPPs and WFs in one site or nearby has many benefits and obstacles as well. This coupling can help in the geographical distribution of WFs along the countries territories by installing WFs at or near to the NPP area. This geographical distribution will make use of the low density population area around NPPs and smoothen the WF’s output power injected into the grid. Due to wind speed fluctuations, the value of the output of WFs’ power is less than their installed capacity. Thus, WFs’ capacity credit is evaluated to find out the corresponding value of the thermal power plants to be installed in the grid in order to satisfy the required system reliability. In this paper, the implementation aspects of NPP and WF coupling/adjacency will be discussed in detail. Based on international experience and literature reviews, the benefits and obstacles of this coupling/adjacency are studied and evaluated. Various case studies are carried out to verify the coupling/adjacency concept. The benefits of WF geographical distribution are examined on two candidate sites in Egypt. The WF capacity credit is calculated by implementing the PJM method using actual three-year hourly wind data. The obtained results are evaluated to study their applicability in the Egyptian environment and their applicability for countries in the Gulf region. Finally, both the coupling idea and the capacity credit values can be used to help decision makers in the planning phase as well as in the selection of WT characteristics as discussed in this paper.
