In order to meet needs of reliability and speediness of power transformer protection, and to have protection blocking reliably in the presence of magnetizing inrush current, the wavelet transform is applied to the discrimination between inrush current and fault current
本文把小波變換應用於勵磁涌流的鑒別，詳細探討了用小波變換來區分勵磁涌流和故障電流的具體方法，提出了兩種比較適用於工程實際的方法。 -
In order to improve the behavior of transformer protection that is incomplete at present in distinguishing magnetizing inrush current from fault current, the paper puts forward a kind of new principle of transformer differential protection after analyzing the characteristic of magnetizing inrush and active power consume of transformers. this protection uses differential protection based on positive sequence active power as a criterion to discriminate internal faults from magnetizing inrush, and ratio restraint differential current protection as a signal to touch off the protection
針對當前電力系統中變壓器保護由於勵磁涌流鑒別理論不完善而導致的誤動率相對較高的問題，論文在分析了變壓器勵磁涌流特性和有功損耗的基礎上，提出了用變壓器正序有功功率差動作為區別勵磁涌流和故障電流的判據，並以成熟的比率制動差流保護作為內外部故障判據的變壓器主保護。 -
This thesis chooses b spline wavelet that adapts to the analysis of power system signal, and uses the wavelet transformer to analyze the magnetizing inrush current and inner fault current. a transformer microcomputer protection was designed in this thesis, and in the base of intermission angle principle, a new criterion was established, which pierces through the traditional method with accurate measurement of intermission angle, but analyses the wave by wavelet transform. this criterion is lower in hardware, so it will be realized in the existing hardware
本文選擇適合電力系統信號分析的b樣條函數作為母小波，對勵磁涌流和內部故障電流進行小波分析，並設計微機型變壓器保護基本配置，在以往間斷角原理鑒別勵磁涌流的基礎上，突破傳統精確測量勵磁涌流間斷角的方法，直接對信號小波變換后的波形進行分析，建立一個新的鑒別勵磁涌流判據，該判據對硬體要求不高，可以在現有一般硬體平臺上實現；並編寫以b樣條函數為母小波的小波變換判據演算法程序。 -
This method can effectively compensate the current error caused by magnetizing current at power frequency. 3 ) because most current transformers have the turn compensation, the characteristic of which was analyzed and the anti - turn compensation model was adopted to offset the action for current transformer with turn compensation
（ 3 ）針對電力系統中大部分互感器都採用了匝數補償的特點，分析了匝數補償的特點，採用了反匝數補償方法，以抵消匝數補償對電流互感器誤差特性的影響，恢復電流互感器原有誤差特性，確保基於物理相似原理有源補償方法的補償效果。 -
Those algorithms are reviewed, and their disadvantages are proposed. this thesis provides a new approach for protecting power transformers. the technique uses positive - and negative - sequence impedance and variation of magnetizing impedance, where phase voltages are used
