By calculating the morphological gradient between the peak and the bottom point of waveform, three-area-compare algorithm is originally put forward, which can be used to make the qualitative discrimination between the inrush and fault current. 在计算电流波形峰谷点之间的数学形态梯度的基础上,提出了一种三面积比较法,用于识别变压器励磁涌流和故障电流。
At present, the plan and development of waterfront city in our country is mostly in a peak period of develop and construction, is also the key point of the current city development and studies. 目前,我国滨水城市的规划开发大多处于一个发展建设的高峰时期,同时也是当前城市发展和研究的重点。
