The invention relates to a method for transformer fault graphic early warning. The method is a wireframe model method. When a wireframe model is adopted to extract data, a top point and seamed edges of only an entity need to be recorded. Compared with surface modeling and entity modeling, the entity modeling is simpler. Due to the fact that the method is different from an existing three-dimensional model method which needs to record all points, lines and surfaces in a three-dimensional model entity, the method only needs to record the top point and the seamed edges, the data size which needs to be calculated is smaller, and the calculating speed is faster. The method solves the problem that a transformer fault graphic early warning system is slow in real-time response.

The invention relates to a data version control method. The method builds a control process of a Petri net customer premises network (CPN) simulated data version. The Petri net bank comprises a data version bank and an operator bank. Supporting willing with different colors represents data with different versions. When operators update the data, a triggering source is changed so that the operator bank receives the information of the operators and simulates the forming process of the data version through the different triggering change. The formed latest data version is stored in the latest data version bank; the historical data versions are stored in the historical data version bank, so that the later inquiry is convenient. By triggering the redundancy and combining the change, the redundant data is combined. Problems of concurrence and combination in the updating process of the data versions are effectively solved. The consistency and integrity of the data are guaranteed, and the management ...

The invention relates to a transformer fault diagnosis method based on a fuzzy Petri net. The method comprises the steps of firstly, constructing a transformer fault diagnosis model by using the fuzzy Petri net; performing separation by using a gas chromatography to obtain a concentration value of gas in transformer oil; acquiring the increase speed of the gas in the transformer oil through a gas generation rate formula; an obtaining initial identification of a model through combination of the concentration value and the gas generation rate of the gas in the comprehensive transformer oil; and performing rational analysis of transformer fault diagnosis by using the transformer fault diagnosis model to obtain a diagnosis result. According to the transformer fault diagnosis method based on the fuzzy Petri net, weighted sum of values of values on input arcs of the processed transitional range of input places serve as the fault possibility, so that the problems such as missing determination, ...

The invention discloses a combined failure causal chain decoupling method of a discrete event system. The combined failure causal chain decoupling method comprises the following steps: performing modeling on the discrete event system by adopting an expansion time Petri net according to an observation event set and a relationship set of failures; obtaining a time-probability Petri net model according to an inversion algorithm of the expansion time Petri net; performing reasoning analysis on the discrete event system by adopting the time-probability Petri net model; and performing decoupling and analysis of a causal china on the reasoning result of the time-probability Petri net model according to a time-probability decoupling algorithm of the causal chain and an analysis algorithm of a pure failure causal chain.
