In order to improve the diagnosis ability of dissolved gas analysis, a novel method for the power transformer fault diagnosis based on gray cloud model is proposed. Softening factor is introduced via entropy theory, and the classification limit single value for canonical matrix of the power transformer fault diagnosis is transformed into the concept of interval numbers limit value. The gray cloud model is used to reflect the fuzziness and randomness of the classification limit value for the power transformer fault diagnosis, which is composed of the peak value, the boundary value of left and right endpoint, the entropy, and the hyper entropy. The subjectivity of the diagnosis results is effectively reduced by establishing the importance information unascertained rational numbers of indicators for the power transformer fault diagnosis, through which the weight value of each index is obtained. A gray clustering algorithm based on gray cloud whitening weighting function is used to analyze and judge the fault pattern of the power transformer. The actual numerical example results show that the proposed method has high degree of diagnosis accuracy, and is characterized by fast diagnosis and good real-time, demonstrating the model is practical and effective.

Aiming at many kinds of uncertain information in the power generation system reliability evaluation under the electric power market condition, a power generation system reliability flexible evaluation model which contains evaluation theory, evaluation index, and evaluation method is proposed based on blind number theory. This model uses the blind number to express node information, which effectively deals with the impact of primitive parameter uncertainty on the reliability evaluation. The reliability index's sensitivity formula is used to effectively find the weak link restricting system reliability, and then the reliability cost-benefit assessment for the power generation system is carried out. The numerical example of IEEE-24 buses reliability test system demonstrates the correctness and availability of the proposed approach.

The microprocessor-relay protection device has gradually replaced regular simulation relay protection it is also difficult to visually determine protection device malfunction or tripping. Therefore, the use of the Mat lab toolbox to build transformer differential protection simulation model, the simulation results show that two-line ratio brake can correctly identify internal fault current, and rapidly remove fault, and the system also can provide convenient for microprocessor transformer protection. © (2013) Trans Tech Publications, Switzerland.
