大型电力变压器振动法故障诊断的现状与趋势

设计了一套桂林电网中短期负荷预测系统。该系统具有自动化运行功能，自动接收各种负荷和气象数据、自动做出预测并定时向中调部门上传预报结果。此系统自2007年开始投运，2007年10月14日－10月31日的预测结果显示，平均日负荷预测准确率为95．98％，达到广西电网调度中心的考核标准。

Status and Trend of Large Power Transformer's Faults Diagnosis with the Vibration Method

Developing fast in recent years, the vibration method becomes a powerful substantial supplement of the traditional method for power transformer's faults diagnosis, and especially for the large power transformer it takes a more and more important position. This paper analyzes the principle, function and technic requirments of the vibration method faults diagnosis, focusing on the key issues of the vibration method faults diagnosis in combination with correlative codes on transforms, and the development trend and the notable technology aspects of the vibration method faults diagnosis.
