In order to limit the short circuit current (SCC) in the power system, bus separate operation is the most simple, effective and economical way. When limiting the SCC by using the method of bus separation, the specific switch of the bus is usually broken after the topology of the in-out lines of bus are fixed, but the influence of the arrangement of the bus in-out lines and the mode of bus separation on the effect of SCC limitation is not considered. Based on the virtual branch method, this paper studies the influence of the bus in-out line arrangement and mode of bus separation on the node SCC, and takes the SCC as the optimization target, so as to get the optimal scheme. From the node impedance matrix, this method illustrates the influence of bus separation mode and in-out line arrangement on the SCC. Finally, the effectiveness of this method is analyzed and verified in IEEE39 node standard network. The example shows that the result of the model is consistent with the conventional enumeration method, but the enumeration times are reduced by more than half.

In this paper, the braking torque of the surface mounted permanent magnet (SPM) motor for the electric sliding plug door (ESPD) system of the rail transport is studied. When the three-phase armature coils are short- circuited, the braking torque should be small to ensure passengers can open the door by themselves. The relationship between the impedance of the three-phase armature coils and the braking torque is deduced. The variation law of motor stator phase resistance and braking torque is obtained. The output torque and braking torque of motor with different stator phase resistance is compared. The model of the motor is built. A prototype of 12-slot/10-pole surface mounted permanent magnet synchronous (SPM) motor is designed and manufactured. The results of the experiment agree well with the theoretical and FE-simulation results.

Miller capacitor (Cgd) and common source inductor (Lscom) are two major feedback parameters across gate driver loop and power loop for power devices. Silicon Carbide (SiC) power transistors have fast switching speed but are more inclined to be affected by parasitics, such as overshoots, oscillations and cross-talk. To ensure a reliable and efficient SiC switching, the impacts of miller capacitor and common source inductor need to be identified and quantified. Since these two parameters are coupled between two loops, a comprehensive analytical analysis is quite complicated and requires massive computation. Therefore, a novel SiC device modeling based upon Cgd and Lscom decoupling is proposed. By extracted the equivalent model for Cgd and Lscom at different switching intervals, gate driver loop and main power loop can be fully decoupled. By doing so, the designs and optimizations for the two loops will be more straightforward and precise. With the proposed decoupling modeling approach, the decoupled equivalent circuit is verified to have descent accuracy in predicting the actual SiC switching transients.

The measurement of grounding impedance has a high requirement for the instrument. In this paper, a method of measuring the power frequency interval wave of large-scale grounding device is proposed, which is studied from three aspects: principle, implementation and field application. The interval wave method outputs the interval voltage signal of power frequency through synchronous high-speed acquisition and power electronic switch, and then removes the influence of field noise by forward and backward difference of adjacent cycle signal. The noise of different types of strong interference is measured in the field, and the denoise performance of the interval wave method is analyzed by simulation. The application of the interval wave method in the measurement of the grounding impedance of a 500kV substation is realized, and the effectiveness of the method is proved by comparing with the different frequency method. The research results of this paper provide a reference for the lightening and intelligence of grounding impedance measurement equipment.

Maximum power point tracking (MPPT) technology is widely used to achieve high-efficiency output of photovoltaic system under the changing irradiation and temperature conditions. To improve the efficiency of the photovoltaic system, a MPPT control strategy based on neural network and incremental conductance (ANN-INC) is proposed in this paper. In ANN-INC, the output of the trained neural network is transferred to the INC part as the initial duty cycle, which makes the initial duty cycle have a small gap with the duty cycle when the photovoltaic system works at MPP, then the INC part can select a small step size to make the output of the photovoltaic system closer to expected output. The strategy has simple structure, fast dynamic response speed, small steady-state power oscillations and high efficiency. The strategy also performs well when the irradiation changes rapidly. The superiority of the strategy is verified in Matlab / Simulink.

In order to solve the problems of subjectivity, limitation of decision method and only considering the defect of single fuzziness in transformer condition assessment, a condition assessment method of power transformer based on fuzzy nearness degree and improved cloud matter-element model is proposed. Considering the randomness and fuzziness of transformer at the condition level boundary, the cloud matterelement model is used to construct the basic framework of condition assessment. Then, in order to take into account the clarity and fuzziness of the "3En" rule and the "50% association degree" rule, and to avoid conflicts of condition conclusions, cloud matter-element model is improved by cloud entropy optimization algorithm to calculate the membership degree of corresponding level of evaluation index. In addition, based on the multi-objective classification algorithm of fuzzy nearness degree, the evaluation index and asymmetric nearness degree vector of each condition level are calculated, the positive and negative ideal levels are determined by Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), and the condition of the transformer is determined according to each asymmetric nearness degree vector and symmetric nearness degree of the positive and negative ideal levels. Taking two 220kV oil-immersed power transformers as examples, the validity and accuracy of the method are proved.

In electromagnetic launch systems, coaxial cables are used for energy transmission from the power supply to the launcher. Once the cable has a short-circuit fault, it will cause the cable to over-current or even explode, causing the launch to fail. This paper first established the dynamic launch model of the capacitive energy storage electromagnetic launch system, and analyzed in detail the influence of the coaxial cable short-circuit fault location on the load current, projectile exit speed, and coaxial cable current. The results show that the closer the short-circuit fault location is to the load side, The larger the cable fault current, the smaller the projectile exit velocity.At 1m the cable fault current reached 1.9 times the normal current, resulting in a 76% drop in exit speed.Secondly,an electromagnetic launch system model with a high-temperature superconducting current limiter was established,and the installation position of the current limiter was optimized. The fault current before and after the installation of the current limiter was simulated and compared. The results showed that: after the current limiter was added, the cable short-circuit current The peak value dropped by 29%, and the projectile exit speed was reduced by 61 % compared to normal conditions, which can effectively reduce the impact of short-circuit current on the cable, increase the projectile exit speed, and provide guidance for the safety design of the electromagnetic launch system.

Bubble is a serious threaten to the insulation performance of oil-paper insulation system in oil-immersed transformer. The vibration will cause alternating pressure changes in oil and then produce cavitation bubbles. However, the cavitation threshold have not been studied in the electrical field. In this paper, the cavitation threshold in transformer oil is calculated by using the relevant theories of fluid mechanics and bubble dynamics, and then the cavitation threshold under different gas contents is obtained by combining experiment and simulation. It is found that the two results have good consistency. The results show that the cavitation threshold of transformer oil decreases with the increase of gas content and temperature, but presents a certain saturation characteristic with the increase of gas content.
