“…A type of high-speed train traction drive system is mainly composed of a pantograph, traction and current transformers, an inverter, and a traction motor which uses the MT205 motor to form a traction drive system as shown in Figure 3 [17]. A fault injection module was built to simulate and inject the early weak fault of a broken rotor bar on the hardwarein-the-loop fault injection benchmark of a certain type of traction drive control system based on dSPACE [18][19][20]. The fault injection simulation platform can be download on the website http://gfist.csu.edu.cn/indexE.html.…”

Aiming at the destructive and irreversible problems of the broken rotor bar fault of the traction motor, the current characteristics of the early weak fault of the single bar are analyzed, and the broken rotor bar fault simulation injection is realized on the experimental platform. Firstly, a damage factor from the change rule of the metal resistance value of a rotor bar is defined. By means of such a damage factor, the relationship between the severity of the fracture of a single rotor bar and the phase resistance of the traction motor was obtained. Through the superposition principle, the traction motor in the fault of the rotor bar was regarded as a normal motor in which the reverse current source was superimposed on the fault rotor bar. The characteristic values of the stator current fault component were obtained when the single bar had broken. Finally, the relationship between the fault characteristics component of the stator current and the fracture severity of the single rotor bar was established. On this basis, on hardware-in-the-loop fault injection benchmark of the traction drive control system based on dSPACE, the gradual injection of early weak faults in the early broken rotor bar was carried out and the results were analyzed. The experimental data demonstrated the correctness of the current characteristics analysis and fault injection.

“…In abc static coordinate frame, every work period of the three-phase four-switch converter is divided into four sectors by four basic space voltage vectors. The sector formed by two adjacent basic space voltage vectors V z and V z+1 is named as N z , where (z, z + 1) can be (1, 2), (2, 3), (3,4) and (4, 1), as shown in Figure 2. The voltage state equation of the motor emulator can be expressed as:…”

This paper presents a power loss decrease method based on finite set model predictive control (FSMPC) with delay compensation for a motor emulator with reduced switch count. Specifically, the topology and mathematical model of the proposed motor emulator with reduced switch count are firstly built. Secondly, in light of given instructions, the normal or fault reference current of the motor emulator is set by a reference current setter. Then delay compensation is applied for the predictive current model to calculate the current residual generated by each switch control signal, and the current tracking performance under actions of two adjacent switch control signals is evaluated for each sector. Finally, a switch power loss objective function is defined, then the two adjacent switch control signals that generate the lowest switch power loss are selected for the next second instant, which minimizes the power loss of the motor emulator with ensuring satisfied current tracking performance. Simulation and experimental results show the feasibility and effectiveness of the proposed method.

“…The attention focusing on modeling of power converters with open-circuit faults is rare. Recently, a fault-injection platform has been developed in [21] and used for validation of various fault detection methods in [22,23]; it is not a mathematical model, but a circuit model. According to circuit topology, the fault-injection platform is established by commercial encapsulated modules.…”

This paper proposes a new modeling method for power converter based on single arm model. The objective of this paper is twofold: (1) One is to present the single arm model with good portability. The single arm model can be used to build the models of power converters which have several arms with the same structure; (2) the other is that the converter model built by the single arm model can represent the power converter when open-circuit faults happened in power devices and clamping diodes. First of all, the inputs and outputs of single arm are redefined. Then, the open-circuit faults occurring in different power devices and clamping diodes are analyzed. Furthermore the single arm model is built. Finally, the model of power converter is established based on the single arm model, which can express the power converter with open-circuit fault. The effectiveness and accuracy of the proposed model have been verified by simulation and experiment results.
