AC transfer systems in Dubai UAE are a new technology in the electrical industry. This AC current transmission system is used to increase the ability to transmit power and control the power consumption of the components of an electrical device. ac transfer systems in Dubai UAE use electronic power controllers and other static controllers to implement this control.
Introduction of AC transfer systems in Dubai UAE
AC transfer systems in Dubai are devices with constant electric power that are installed in AC transmission networks in order to increase capabilities such as power transfer capability, stability and network control. Other applications of these devices are to manage congestion and optimize energy loss. The controllers used in this device include Static Synchronous Series Compensator (SSSC) and Thyristor Controlled Series Capacitor (TCSC), which provide series compensation for the reactance of the lines they are connected to. In general, static synchronous compensator (STATCOM) and static VAR compensator (SVC) (where VAR stands for reactive volt-ampere) are AC transfer systems devices that provide shunt compensation for transmission lines. AC transfer systems also act as a driver in robust control schemes and PMU-based wide area control schemes to provide adequate damping of inter-area oscillations.
Applications of AC transfer systems offshore
AC transfer systems in UAE have been used in various industries such as shipping for about three decades. These alternating current transmission systems have provided better performance than the previous devices and are more successful in controlling the current of the transmission line, controlling the voltage, improving the transient stability and damping the oscillation. The application of AC transfer systems in UAE is increasing because their advantages are becoming more and more obvious to power system engineers and researchers. In general, the controllers of AC transfer systems in UAE are designed to operate at the base power frequency in sinusoidal conditions and do not necessarily improve the quality of electrical power. In fact, most controllers of AC transfer systems in UAE use switching devices that inject current and voltage harmonics into power systems. Optimization approaches (eg, sinusoidal PWM techniques) have been proposed to minimize their limitations.
AC transfer systems in Dubai UAE are divided into three types (series, shunt, combined devices). In the continuation of this section, we will examine the applications of AC transfer systems in Dubai.
For example, the power ratings of converters range from a few MW to hundreds of MW, and the switching frequency is lower compared to the switching frequency used in industrial application converters to avoid excessive switching losses. However, there are several types of switching control, the most well-known of which are by far:
In AC transfer systems in Dubai, the power of the converters varies from a few megawatts to hundreds of megawatts, and the switching frequency is lower than the switching frequency used in industrial application converters to avoid excessive switching losses. However, there are different types of switching control.
Why do we use AC transmission systems?
AC transfer systems in Dubai UAE are resources with new technology that can overcome certain limitations in the static and dynamic transfer capacity of electrical networks. The main goal of using these systems is to supply the network with inductive or capacitive reactive power as quickly as possible according to its specific needs, while improving the quality of transmission and the efficiency of the power transmission system.
Characteristics of alternating AC transmission systems
• Quick voltage adjustment
• Increased power transmission in long AC lines
• Damping of active power fluctuations
• Load flow control in grid systems
Due to the features that AC transfer systems in Dubai UAE have, it improves stability and performance in existing transfer systems. Therefore, AC transmission systems on ships can make better use of their existing transmission networks, significantly increase the availability and reliability of their linear networks, and improve dynamic and transient network stability while ensuring better quality. do
AC transfer systems in UAE is a device used in powerful systems due to its applicability to increase the stability of voltage, angle and frequency of the power system.
There are two main approaches of AC transmission systems in UAE to stabilize the AC power transmission network. The first approach is shunt compensators where capacitor banks and inductors are connected in a shunt configuration to inject reactive power. The second approach uses capacitor banks connected in series with the grid line, which can be switched in and out using power devices.
What is Flexible AC transmission system?
Flexible alternating current transmission system (FACTS) is a system consisting of static equipment used to transmit electrical energy. Its purpose is to improve the controllability and increase the power transmission ability of the network. This system is generally a device based on power electronics. A flexible alternating current transmission system is defined by the Society of Electrical and Electronics Engineers (IEEE) as: "A system based on power electronics and other static equipment that controls one or more parameters." The power transmission system realizes alternating current to improve controllability and increase the ability to transmit electrical power.
This part of the article is responsible for introducing new tools of modern energy transmission systems, which will create a great transformation in the exploitation and control of power systems. With the increasing consumption, energy transmission systems are facing a crisis of power transmission limitations. These limitations are actually due to maintaining the stability and providing the permitted voltage level. Therefore, the practical operating capacity of the transmission lines is much lower than the actual capacity of the lines, which is the same as their thermal limit. This causes a lack of use.
AC transmission systems will be optimized. One of the ways to increase the power transmission capacity is to build new lines, which is not so simple and brings many problems.
With the progress of the semiconductor industry and their use in the power system, the concept of flexible energy transmission systems (FACTS) was proposed to use the actual capacity of the transmission system without building new lines. The recent progress of the electronics industry in the design of semiconductor switches with the ability to turn off And its use in voltage source converters at the level of power and voltage of the power system, in addition to introducing newer devices, will create a revolution in the concept of FACTS and will make energy transmission systems much more efficient and effective. In order to better understand and introduce the outstanding characteristics of these devices, first of all, it is necessary to identify the existing problems of energy transmission systems. Then the classical solutions to solve them are expressed. The voltage source converters, on which the structure of all new FACTS devices is based It will be discussed next and finally the new generation of FACTS tools will be introduced.
