On-load Parallel Transformer Automatic Voltage Controller Technology

In the electricity transmission, for distribution in the transformer as the transformer's core equipment playing a leading role, the application is extremely broad. In order to improve power supply reliability and economy, the modern power system were powered by a transformer on-load tap transformer parallel operation of technology and techniques. The current parallel operation of on-load tap transformer voltage regulation when the network access by trained electricians manually operated, while manual adjustment difficult to cope with power shortage, caused by mains voltage fluctuations and frequent voltage operation, On the other hand the status of equipment can not ensure accurate automated synchronization and totally reliable. In order to meet market demand for electric power systems, and we consider the development of a new type of automatic on-load voltage controllers, analog manual control methods, to achieve parallel operation OLTC voltage automatically adjusted.This paper describes the automatic parallel-load voltage of the regulator target voltage conditions, voltage during the many problems faced, as well as a variety of problem solving principles and solutions.This paper describes the design of parallel operation, the construction of transformer automatic voltage control, software logic, application of principles, how to complete the parallel operation of automatic on-load tap transformer.This paper describes the device to complete intelligent automatic functions tied OLTC process, while existing data processing and preservation of information, data and remote scheduling interaction, control and remote voltage regulator scheduling effort.
