摘要
为了解决电力变压器中故障预测存在的大量随机性和模糊性问题,针对矿用变压器故障数据少的情况,采用了灰色系统理论对其进行灰建模和灰预测。通过灰建模的可行性,阐述了灰建模基本步骤,通过实例验证了该方法的有效性和适用性,为矿山超前采取防范措施,提供了依据,将故障损失减小到最低,具有实际推广价值。
To solve large randomness and fuzziness problems of the fault forecasting in power transformer, according to the mining transformers fault datas lack, the grey theory is used, the grey forecasting model is established and forecasted. The feasibility of grey forecasting model is verified. The basic steps of grey forecasting model is discussed. The validity and applicability is analyzed through example. Thereby the reference of advance countermeasure distributed in the mining. The accident loss is reduced the minimum. It has the value of practice promotion.
