Power engineering, also called power systems engineering, is a subfield of energy engineering and electrical engineering that deals with the generation, transmission, distribution and utilization of electric power and the electrical devices connected to such systems including generators, motors and transformers. Although much of the field is concerned with the problems of three-phase AC power – the standard for large-scale power transmission and distribution across the modern world – a significant fraction of the field is concerned with the conversion between AC and DC power and the development of specialized power systems such as those used in aircraft or for electric railway networks. Power engineering draws the majority of its theoretical base from electrical engineering and while some power engineers could be considered energy engineers, energy engineers often do not have the theoretical electrical engineering background to understand power engineering.

Power Engineering deals with the generation, transmission, distribution and utilization of electricity as well as the design of a range of related devices. These include transformers, electric generators, electric motors and power electronics.

The power grid is an electrical network that connects a variety of electric generators to the users of electric power. Users purchase electricity from the grid so that they do not need to generate their own. Power engineers may work on the design and maintenance of the power grid as well as the power systems that connect to it. Such systems are called on-grid power systems and may supply the grid with additional power, draw power from the grid or do both. The grid is designed and managed using software that performs simulations of power flows.

Power engineers may also work on systems that do not connect to the grid. These systems are called off-grid power systems and may be used in preference to on-grid systems for a variety of reasons. For example, in remote locations it may be cheaper for a mine to generate its own power rather than pay for connection to the grid and in most mobile applications connection to the grid is simply not practical.

Today, most grids adopt three-phase electric power with alternating current. This choice can be partly attributed to the ease with which this type of power can be generated, transformed and used. Often (especially in the United States), the power is split before it reaches residential customers whose low-power appliances rely upon single-phase electric power. However, many larger industries and organizations still prefer to receive the three-phase power directly because it can be used to drive highly efficient electric motors such as three-phase induction motors.

Transformers play an important role in power transmission because they allow power to be converted to and from higher voltages. This is important because higher voltages suffer less power loss during transmission. This is because higher voltages allow for lower current to deliver the same amount of power, as power is the product of the two. Thus, as the voltage steps up, the current steps down. It is the current flowing through the components that result in both the losses and the subsequent heating. These losses, appearing in the form of heat, are equal to the current squared times the electrical resistance through which the current flows, so as the voltage goes up the losses are dramatically reduced.

For these reasons, electrical substations exist throughout power grids to convert power to higher voltages before transmission and to lower voltages suitable for appliances after transmission.

Power engineering is a network of interconnected components which convert different forms of energy to electrical energy. Modern power engineering consists of four main subsystems: the generation subsystem, the transmission subsystem, the distribution subsystem and the utilization subsystem. In the generation subsystem, the power plant produces the electricity. The transmission subsystem transmits the electricity to the load centers. The distribution subsystem continues to transmit the power to the customers. The utilization system is concerned with the different uses of electrical energy like illumination, refrigeration, traction, electric drives, etc. Utilization is a very recent concept in Power engineering.

• Question: What is the cost of applying through ACASC?

Answer: ACASC charges a service fee of 50$ for using its online application portal. Applying through ACASC into Chinese universities attracts a service fee of $50.

• Question: Can I apply to the university directly?

Answer: Yes. ACASC gives the applicants, the chance to directly apply to their desired universities through our online application portal. We have synchronized our system to create a simple platform that connects universities and colleges in China to international students all around the world.

• Question: How can I track my application status?

Answer: To track the application status, please log in your ACASC personal account. Whenever there’s an update, you will be informed on your application status through ACASC system within a day as soon as we receive university’s notification. You will simultaneously receive ACASC auto-email about the application status. To directly inquire about your application status, feel free to send us an email to admission@acasc.cn and our team will keep you updated.

• Question: How to deal with a pending application?

Answer: When an application is pending a decision it means that your school has received it and no admissions decision has been made yet. The admissions office may have reviewed your application package or may not have.

The main cause of a pending application is usually incomplete application documents. As a result you will be requested by the school’s admission office to re-check and modify all submitted application documents or perhaps even add extra documents and then re-submit them.

To avoid further delays, carefully read the university’s comments, modify your application form on ACASC, and re-upload the required application documents. You can contact ACASC on admission@acasc.cn for any help with regards to your pending application

• How long does it take to process my application?

Processing time varies for different applications. For example to process a degree program application requires more time than a Chinese language application. Confirmation for Chinese language application by the admission office usually takes 2 to 4 weeks. However, time for degree programs application differs. For example fall semester application processing is after March, and it takes a period of 1 to 2 months. This also depends on your qualification and the number of applicants.
