The Design Of Online Monitoring System Of Smart Substation Transformer

Transformer power system as an important device, once out of the scope of failure is great, and the service is too much trouble and longer, often caused by a wide range of long power outages that may affect people’s daily lives and industrial and agriculture. Therefore, to determine if the device is functioning properly through a variety of indicators for monitoring equipment has failed, even to predict faults, transformer equipment to ensure safe operation. Uncler China’s current construction of smart grid background, epoch-making significance.The main work is based on transforming gradually started on the basis of on-line monitoring, the main focus is on the state line monitoring trans formers. The existing electrical equipment monitoring equipment and technology for a detailed explanation and description, the overall design is proposed substation transformer on-line monitoring system, focusing on the realization of on-line monitoring system. Analysis shows that the system reliability and stability can achieve a satisfactory degree, to improve the safety and reliability of the transformer played an important role. The application of different technologies in the system, including sensor technology, IT technology, communications technology. The system utilizes a variety of the collected data about the status of the transformer, that the operating state of the transformer. When the transformer fails to make a timely diagnosis, knowing the type of failure and solutions, an alarm signal to the staff.This article from the system functional requirements analysis and study, through in-depth study of the common faults and transformer monitoring technology, whereby the overall design of the system architecture program, then the system hardware module design, and the transformer fault diagnosis Specific applications carefully study design. By installing and using a transformer on-line monitoring system and monitored through several case demonstrates the accuracy, practicality and stability of the monitoring system. In order to ensure the safe operation of the power grid, improve equipment life, protect the safety of operating personnel, reduce maintenance costs of equipment, for us to build a smart grid to provide a force.
