Using the user-defined model (UDM) provided by the power system analysis software package ( PSASP), This paper constructs traction power supply system model. The correctness of interface between user-defined model and PSASP is verified by independent dynamic characteristic program. It offers a new way of available practical model applying to power system simulation and research on the influence of traction loads to power system.

More Electric Aircraft

Based on the mathematical model of synchronous electric machine, basing on permanent magnets, presented in this paper, the key importance of alternator AC power sources in the form of generator (for conventional aircraft) and in the form of integrated unit starter/AC synchronous generator S/G AC (with respect to advanced aircraft concept in the field of more/all electric power MEA/AEA) was highlighted. In addition, through the analysis and selected simulations of the power supply system of a modern aircrafts, sources of onboard electrical energy (synchronous generator, integrated unit starter/AC generator) were located in board autonomic power system ASE (EPS, PES). Key components of this system are the electro-energetic power system EPS and the energo-electronic power system PES. Additionally, the analysis and exemplary simulations of key electricity sources based on mathematical models have contributed to highlighting the main practical applications in line with the trend of a more electric aircraft.

Based on the analysis and mathematical models of synchronous electric machines (motor/generator), basing on permanent magnets, presented in this paper, the main importance of alternator AC power sources in the form of starter/generator (for conventional aircraft) and in the form of integrated unit starter (motor)/AC synchronous generator S/G AC (with respect to advanced aircraft concept in terms of more electric aircraft) was highlighted. Additionally, through the analysis and selected simulations of the on-board autonomous power supply system of the modern aircrafts, sources of electrical energy (synchronous motor/generator, integrated unit starter/AC generator) were located in board autonomic power system ASE (EPS, PES). Main components of this system are the electro-energetic power system EPS and the energo-electronic power system PES. In addition, the analysis and exemplary simulations of main electricity sources based on mathematical models have contributed to highlighting the main practical applications in accordance with the concept of MEA.

Traction Power Supply

Traction load in electrified railway result in the power supply system contains a lot of negative sequence, harmonic and reactive current. It is necessary to analysis the compensation principle based on active compensation of electrified railway traction power supply system. According to the relation between primary winding and secondary winding of regular traction transformer, we deduced general voltage and general current transform formula, and then deduced completely and negative sequence compensation formulas. It also gives the method of reduce active compensation capacity.
