摘要:
MOV静态下的功率损耗是影响其热稳定的重要因素,在考虑了老化因素对MOV功率损耗的影响后提出了老化程度变量并将其量化的新方法,并利用自适应模糊推理系统(ANFIS)将电压(V)、温度(T)、老化程度(AD)作为网络的输入,实验测量数据作为训练样本对MOV的功率损耗进行评估。研究表明:ANFIS可有效评估MOV的功率损耗,其最大相对误差为8.15%,为MOV功率损耗特性研究提供了新的途径; MOV静态下的功率损耗随着其老化程度的增大而增加,且与温度成正相关; 功率损耗的增加率在65 ℃附近出现拐点,MOV的温度低于此温度时功率损耗随着温度的增加较缓慢,MOV的温度高于此温度时功率损耗随着温度的增加较快,拐点温度取决于MOV的老化程度。
Abstract:
The power loss of MOV is an important factor affecting the thermal stabilityunder static operation condition. In order to obtain the power loss of MOV accurately, the influence of aging factor on the power loss of MOV has been considered. Furthermore, the aging degree variable has been proposed and quantitated in this paper. The applied voltage, temperature and agingdegree were considered as inputs, the experimental data as the training sample in adaptive fuzzy inference system(ANFIS)to evaluate the power loss of the MOV. The study shows that the ANFIS can effectively evaluate the power loss of MOV, and the maximum relative error is 8.15%. It provides a new approach for the study of MOV power loss characteristics. The power loss of MOV understatic operation condition increases with its aging degree and the temperature. The increase rate of power loss shows inflection point near 65 ℃, which is called inflection point temperature. When the temperature is less than the inflection point temperature, increasing rate of power loss is slow; however, when temperature is bigger than the inflection point temperature, power loss increases quickly. The value of inflection point temperature is depending on aging degree.
