Description

     The power supply systems must provide maximum reliability and power quality while its costs are to be minimized. These requirements present a major design, operation, and maintenance challenges due to the dilemma between supply improvements and the associated investments. Therefore, the design, operation, and maintenance of power supply systems are usually a compromise between the reliability and quality of supply from one side and the required investments from the other side. The main impacts of power interruptions and low power quality are the costs and safety associated with them. Therefore, electrical loads are classified according to the impacts of interrupting their power supply; loads are classified to non-essential, essential, and critical. The impact of power interruptions on non-essential loads are minor while interruptions have a significant impact on the essential loads, especially if the interruption duration is above a specific threshold value. Critical loads are a class of the loads that should not be interrupted under any circumstances. The hazards, and costs associated with interrupting critical loads are usually intolerable even if the interruption duration is very small.

     For essential and critical loads an alternative safe supply must be available for providing the required reliability and power quality levels. The Uninterruptible Power Supply (UPS) is a main tool for providing safe power supply for these load classes. UPSs have many designs, operation, and control algorithms. The main differences UPS categories are the power capacity, switching time, safe duration, maintenance requirements, available system monitoring, self-diagnosis, and costs. For safe durations from minutes to – for example – an hour, static UPSs are the ideal safe supply alternative while in longer duration electromechanical UPSs provide an economically feasible alternative supply. According to the load requirements and interruption statistics, a justified mix of static and electromechanical UPSs may be chosen for providing an optimal alternative supply. In all cases, the flexibility allowed to deviate from perfect reliability and power quality should be used to allow designing cheaper and simpler alternative supply systems; however, this flexibility should not be wasted by permitting poor maintenance and operating procedures to compromise the reliability and quality.

     There are often cases that the alternative supply systems are not well selected, or incorrectly installed, operated, maintained. In other cases, they do not work properly when needed and this failure caused losses in term of time, money, and safety. Therefore, this training course provides and in-depth analysis of supply requirements for various load classes. In addition, the course surveys various options for providing an adequate supply system considering the design of the power distribution systems up to UPSs. Choice and design of system designs and UPSs are carefully covered within the course. Operation, maintenance, and troubleshooting of various supply alternatives are also considered in this course and typical case studies and simulations are presented.

This course title UPS uninterruptable power supply need to focus only on the main components of the UPS, detail information of the various control boards, as a minimum it shall be discussed with one high reputed manufacturer such as Emerson, AEG, or schneider. Precommissioning and commissioning testing approach is very general.

Sometimes the lecturer's English is not clear and the captions sometimes shows words that are not said at all by the lecturer (sometimes it shows wrong words), also I hoped he explained section 8 that is related to power electronics.

It is extremely theoritical, I would like to see troubleshooting process on a real static UPS and its board/batteries

There is some useful information. However, there is too much background noise, accent is a little difficult to understand sometimes, linguistics and visual illustrations in the slides could be better.

English is not my native language. The subtitles a over diagrams and I can't read part of them. It is good idea to have cource text in PDF.

ingilizcesi çok kötü ne dediği anlaşılmıyor. altyazı bile çok fazla hata içeriyor. bana hiçbirşey katmadı. İçerik çok yetersiz. Daha kaliteli video beklerdim.
