解釋
正序功率-
The fourth chapter was under the title of " fact - affirmation power ", the fifth " law - application power ", and the sixth " proceeding - direction power ". in the first chapter " positive study of the trial power ", beginning with the basic meaning of the civil trial power, the writer gave a brief clearance of the historical development sequence of the trial power ; and upon this, he gave his own opinions about the system guarantee and reform of the moving of the civil trial power. he viewed that as for the guarantee, whe
認為，就我國現行民事審判權運行的制度保障而言，無論是其中的組織制度，還是人事制度，抑或是活動制度都不同程度地存有問題，因此，對組織制度和人事制度應進行相應的變革，而對活動制度則應進一步地落實與完善；同時並認為，對包括民事審判制度在內的司法體制的改革應有統一的領導機構來進行部署和協調，以確保改革的成功。 -
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。 -
On the analysis of the theory of instantaneous reactive power, the paper brings forward a new harmonic detection method based on multiple frequency transform. the detection theory of positive sequence harmonic and negative sequence harmonic is respectively proved in detail. the correlative concepts are defined and the simulation validates the feasibility of this method
本文在分析瞬時無功功率理論的基礎上，提出了一種基於倍頻旋轉變換的諧波測量方法，分別針對正序和負序分量，從理論上證明了該方法能分離出單個的諧波，給出了相關量的定義，最後通過模擬驗證了該方法的有效性。 -
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
本文從機理上對變壓器保護進行新認識，將電壓量引入了變壓器保護中，採用了基於序基頻阻抗突變量和勵磁阻抗變化的變壓器保護方法。 -
Having lower and unified positive ( negative ) and zero sequence impedance, which benefits to improve the power supply quality
