摘要： The invention discloses a method for identifying full parameters of an electric element by a fault recording data, comprising steps: inputting fault recording data related to an electric element; conducting data processing on the fault recording data; identifying full parameters of the element by intercepted data and a differential equation of the full parameters of the element; and outputting an identified result. Further proposed are a system for identifying full parameters of a power generator by fault recording data and a method for locating a line fault point with fault recording data. With the implementation of the invention, a fault resistance and full parameters of an element such as an electric line and a transformer, etc. can be identified. The invention can obtain full parameters of a fault element and also a non-fault element, and the parameters precision would be increased from the current 20% to less than 1%.

摘要： Le dispositif de calcul comporte des filtres numériques (12, 13) non récursifs, à réponse impulsionnelle finie, calculant, à partir d'échantillons prélevés sur une période du réseau, pour au moins deux phases distinctes, deux composantes (X, Y) déphasées entre elles de 90° et représentatives de la grandeur considérée dans la phase considérée. Un calcul matriciel utilisant une matrice de rotation à deux dimensions (18) permet d'en déduire les composantes (Xi, Yi) déphasées entre elles de 90° de la composante inverse. Un tel dispositif de calcul peut être intégré dans un relais, par exemple dans un relais à maximum de courant inverse.

摘要： The fault identification system includes a first logic circuit (Fig. 6) which is responsive to conventional protective elements (81A, 81B, 81C) which recognize the presence of low resistance single line-to-ground faults for the A, B and C phases on a power transmission line. The first logic circuit includes a portion thereof for recognizing and providing an output indication of single line-to-ground faults, faults involving two phases and three-phase faults, in response to the occurrence of different combinations of outputs from the protective elements. A calculation circuit (Fig. 7), when enabled, is used to determine the angular difference between the total zero sequence current and the total negative sequence current for high resistance faults when the protective elements themselves cannot identify fault conditions. The angular difference is in one of three pre-selected angular sectors. An angular difference in the first sector indicates an A phase-to-ground fault or a BC phase-to-phase to ground fault; an angular difference in the second sector indicates a B phase-to-ground fault or a C phase-to-phase to ground fault; and a signal in the third sector indicates a C phase-to-ground fault or an AB phase-to-phase to ground fault. A processor is used to determine which of the two possible for each angle determination is the actual fault type. An output indication of the actual fault type is then provided.

摘要： It is desirable to provide remote digital protection of distribution transformers. A protection system is disclosed which is able to detect increases in transient D.C. current flowing in the respective phases of a distribution cable (10) feeding a transformer and also to detect increases in other selected functions of supply parameters for identifying and quantifying a fault current flowing in the distribution cable (10). Increases in these other functions are analysed to identify whether the increases indicate a fault current. Any such fault current can then be quantified and the triggering of a circuit breaker (19) initiated to isolate the supply cable on identifying a fault current. The circuit breaker (19) is not triggered for any increases in the other functions for as long as there is a detected increase in D.C. current in any phase.

摘要： It is desirable to provide remote digital protection of distribution transformers. A protection system is disclosed which is able to measure parameters of a supply to a distribution cable (10) to a distribution transformer to provide time related values for the positive sequence current, voltage and phase angle. Time related values for the susceptance of the distribution cable (10) and load connected thereto can then be calculated, and monitored to detect increases in negative susceptance. The triggering of a circuit breaker (19) is then initiated to isolate the distributor cable (10) if the increase exceeds a predetermined thershold increase.
