Power electronics building block (PEBB) is a new structure of power electronic equipment based on the concept of standardization. In this paper, a general design method for a high-power PEBB rated for 57.6kW, 1.2kV DC-link is given. The designed PEBB uses 1.7kV SiC MOSFET modules as power devices. The selection of DC-link capacitors is introduced in this paper. The design method of an air-cooled cooling system that contains an aluminum radiator and four DC fans is given. To verify the performance of the cooling system, COMSOL is used to simulate the SiC modules’ temperature under full-power operation. The design schemes of the DC bus-bar and AC ports are also presented. The bus-bar uses a copper-based multilayer laminated bus-bar so that the SiC modules can be connected to the DC-link capacitors in the low-inductance loops. The thermal performance and mechanical strength of the bus-bar are simulated by COMSOL, and the parasitic parameters of it are simulated by Ansys Q3D. In addition, the detection and control methods used in the PEBB are also mentioned. The structure of the PEBB is completed by the integrated layout design. Finally, a 57.6 kW PEBB prototype is built. A pump-back test platform whose topology is a dual active bridge is built through two PEBBs. The experiment shows the temperature rise of SiC modules is low, and the maximum drain-source voltage of the SiC MOSFET is 1244V. The PEBB operates stably and reliably at 56.7kW, and the power density is up to 1920kW/m3.
电力电子构件(PEBB)是一种基于标准化理念的新型电力电子设备结构。本文给出了额定57.6kW、1.2kV直流链路大功率PEBB的一般设计方法。所设计的PEBB采用1.7kV SiC MOSFET模块作为功率器件。本文介绍了直流电容的选择。给出了一种由铝散热器和4个直流风扇组成的风冷冷却系统的设计方法。为了验证冷却系统的性能，使用COMSOL软件模拟了SiC模块在全功率下的温度。给出了直流母线和交流端口的设计方案。母线采用基于铜的多层叠层母线，这样SiC模块就可以连接到低电感回路中的直流电容上。利用COMSOL软件对母线的热性能和机械强度进行了仿真，并用Ansys Q3D软件对母线的寄生参数进行了仿真。此外，还介绍了PEBB的检测和控制方法。通过整体布局设计完成了PEBB的结构设计。最后，建造了一个57.6千瓦的PEBB原型机。通过两个pebb构建了拓扑结构为双有源桥的回抽测试平台。实验表明，SiC模块的温升较低，SiC MOSFET的最大漏源电压为1244V。PEBB运行稳定可靠，功率为56.7kW，功率密度高达1920kW/m3。

The serious problem with distribution insulators is the leakage current resulting from severe contaminant accumulation in coastal areas. To improve the electrical safety operations in distribution system in Taiwan, the application of a deep learning machine is developed to predict the leakage current of insulators. In this project, the deep learning methodology with a large scale of gathered data is developed to predict the insulator leakage current with weather parameters. The hourly leakage currents of 15kV distribution insulators are recorded continuously at outdoor operating conditions as the target variable for more than one year. The gated recurrent unit (GRU) based deep learning machine is utilized to predict the leakage current. The performances of GRU are compared with the RNN model with different benchmarks. The resultant experiments proved that the proposed GRU method is suitable to predict the leakage current.

Buildings have almost a third of total energy consumption. University buildings also have significant energy consumption because of their high usage floor areas and user numbers, as they are heavily used buildings. In order to provide energy efficiency in such buildings, the insulation of the buildings, choosing the systems used in the building as energy efficient, the most appropriate use / operation of these systems and the building are the main factors. On the other hand, behavior of the users is also very effective in energy consumption. It is known that users frequently interfere with windows, especially in buildings that serve a large number of users. The aim of this study is to determine the interventions made by the users on the windows and the effects of these on the energy consumption through the year-round measurements in the selected classes in a university building. Within this scope, measurements of window opening, indoor air temperature, CO2 concentration, and electricity consumption were made in selected classes throughout 2019. Energy consumption model has been developed with the help of measurement results and regression analysis to determine the suggestions and percentages of the building's energy consumption reduction. The measurement results show that the total opening time of the windows in the classes is up to 33.6% of the annual usage time. It has been determined that keeping the windows open for a long time increases the energy consumption of the building by 4.07% in heating mode and 2.63% in cooling mode.

Band-pass filter (BPF) and low-pass filter (LPF) are generally used to extract the position error signal of permanent magnet synchronous linear motor (PMSLM) in the traditional high-frequency (HF) pulsating voltage injection method. However, filters will generate system delay and affect the dynamic performance of the system. Therefore, this paper proposes to combine the generalized second-order integrator (SOGI) and notch filter (NF) to form an improved generalized second-order integrator (SOGI-NF). This structure effectively reduces the time delay caused by signal processing and shortens the operation time by replacing the BPF. Meanwhile, compared with the traditional SOGI, it has stronger harmonic attenuation ability, wider bandwidth and better dynamic performance. Finally, the feasibility and superiority of the position error signal extraction strategy based on the improved second-order generalized integrator are verified by simulation.

With the increase of the proportion of new energy, the regulation resources on the power plant side of the power system are weakened. Mining the load elasticity and transforming it into system regulation resources, and building a new system regulation mode of “source-storage-demand” coordination has become a significant demand of the new power system. The paper summarizes the research status at home and abroad from the following three aspects: electricity consumption behavior and load elasticity, load elasticity modeling and elasticity identification and aggregation effect of load elasticity. Then, it introduces the research challenges and development trends: it is necessary to study the concept and depictive method of axiomatic load elasticity measure and establish axiomatic load elasticity measure index. The typical load elasticity description and modeling method can be studied by means of data-physical doubly drive. The load elasticity aggregation effect and its quantitative evaluation method will be study at the feeder level bus level and grid level.

In the process of signal transmission between ground-fixed balise and vehicle-mounted BTM antenna, it is easily exposed to electromagnetic interference, among which transient pulse interference is the most frequent and serious one. Therefore, it is of great significance to carry out the research on the electromagnetic interference coupling law of onboard BTM antenna and master its interference coupling characteristics for ensuring the normal transmission of train signal. In this paper, firstly, based on the working principle and transmission characteristics of balise system, the simulation modeling of vehicle-mounted BTM antenna is analyzed. Then, the time domain, frequency domain and energy distribution of typical pulse jamming signals are analyzed. Based on the model of vehicle-mounted BTM antenna, the coupling current of vehicle BTM antenna port under the influence of different types, different polarization angles and different incident angles is simulated. The results show that when the pulse interference signal is horizontally polarized, the electromagnetic interference caused to the vehicle-mounted BTM antenna is much greater than that caused by the vertical polarization, and when the incident direction is in the main lobe direction of the vehicle-mounted BTM antenna, the influence on the vehicle-mounted BTM antenna is the largest.

As the proportion of wind power increases, the proportion of synchronous motors in the grid decreases, which reduces the damping and inertia of the power system. At present, the main voltage source control adopts virtual synchronous control. This control strategy can effectively improve the inertia and damping of the system. In this paper, the impedance model of virtual synchronous generator controlled doubly-fed induction generator is established in the synchronous rotation coordinate system. Secondly, the effects of controller parameters and series compensation on system stability are analyzed by using generalized Nyquist criterion. Finally, the correctness of the theoretical analysis is verified by simulation results.

Worldwide energy demand is growing fast because of the population explosion. Technological advancements paved the way toward utilizing renewable energy sources instead of fossil fuels as they cause harmful effects on the environment. To increase the efficiency of a solar PV system, Maximum Power Point Tracking (MPPT) techniques are applied to a power converter that is connected to the PV array. Thus, maximum power is extracted from the PV array. Since sunlight is not always available, a battery is used as a storage device. Traditionally, two two-port converters are used with such systems. Recently, three-port converter that connect the PV, the battery, and the load together using a single converter is introduced in the literature. This paper compares between these two types of converters based on the PV power output when the solar irradiance changes. The simulation is done using MATLAB/SIMULINK software. It is found out that two-port converter responds more efficiently to irradiance changes than the three-port converter. However, three- port converter has more steady attitude when the temperature is constant for a certain amount of time. The significance of this paper reiles on comparing between these two types of converters to determine the best choice for a certain application.
