Study on Intelligent Monitoring System for Oil-Immersed Power Transformer Cooling System Based on Virtual Instrument

摘要: 传统的油浸式电力变压器冷却控制系统常采取在变压器旁设置控制柜的方式对变压器冷却系统进行控制。针对无法远程监控，可靠性低等问题，本文提出一种基于虚拟仪器技术的油浸式变压器冷却智能监控系统，该系统由智能控制柜和以Labview为平台的监控系统组成，根据变压器油温、负荷进行控制，集实时显示变压器及冷却系统工作情况、数据实时存储、强制手动远程控制冷却系统和变压器温度场显示于一体，对变压器的冷却系统进行有效控制与监控。

Abstract: The traditional oil-immersed power transformer cooling control system is often achieved by setting the control cabinet next to the transformer to control the transformer cooling system. In this way, there are some problems such as lack of remote monitoring and necessary data storage capabilities, low reliability and other issues. This paper presents an intelligent monitoring system of oil-immersed transformer cooling system based on virtual instrument technology. The system is composed of intelligent control cabinet and monitoring system with Labview platform. It can control the cooling system according to the transformer oil temperature and load. The other functions include real-time display transformer and cooling system work, real-time data storage, forced manual remote control cooling system and transformer temperature field display, which has an important practical significant for safe operation of transformers.
