Box-type Transformer Embedded Substation Monitoring System Research

Transformer substation as a node in an entire electrical grid, is shouldering the electrical energy transmission and allocation. transformer substation relay protection, the monitoring automated system is guarantees above of mission the foundation. In electrical network unified command and coordinated, electrical network various nodes (for example transformer substation, power plant) the concrete implementation can safeguard electrical network's security, stably, the reliability Operation. Therefore, transformer substation supervisory system is an important component of electrical network automated system, Its pros of the performance of direct impact on the integrated substation automation system as a whole efficient, and safe operation. The box-type transformer substation as a result of its own design structure and the characteristic, put forward a higher request for the transformer substation supervisory system.Along with the voltage class and the electrical network complex degree's enhancement, the power supply radius and distribution capacity's enlargement, uses traditional the transformer substation and Secondary Equipment has more and more with difficulty At the same time satisfied : Reduces the transformer substation construction cost, improve the power supply quality, raise the voltage qualified rate,enhance the transformer substation security reliability and system's operational guidance level, reduce the total investment, reduce the maintenance work load, reduce the attendant labor intensity and so on many request. to this end, it is necessary to research and development of computer technology as the foundation of various levels of voltage substation automation systems to replace or upgrade traditional substation secondary equipment.The present paper take the transformer substation supervisory system present stage's technology as the reference, proposed and has studied one kind based on ARM core high performance embedded microprocessor's transformer substation synthesis automation monitoring system. embark from the current each kind of pattern's transformer substation synthesis automated system structure in this paper, combined computer technology development's tendency, introduced this monitoring system's principle and the constitution and the characteristic in detail. In order to satisfy the Substation supervisory system's timeliness and the processing complex multi-duty need, transplants real-time operating systemμC/OS-Ⅱto the Substation supervisory system's microprocessor. And in theμC/OS-Ⅱoperating system platform, transplants theμC/GUI graphics system, improved the man-machine contact surface; Transplants the FAT filing system, causes the system and other system convenience exchange data; Transplants the LwIP agreement stack, causesμC/OS-Ⅱto support the ethernet communication. Moreover, this system has realized the local/long-distance upgrade function, causes the system to convenient for the maintenance, the renewal, lengthened the product use cycle.
