Description
Technical Field
The invention relates to the field of switched reluctance motor systems, in particular to a high-performance switched reluctance generator converter system with full-inductance direct voltage boosting and forward charging reverse energy feeding and a control method thereof.
Background
Switched reluctance motor receives the industry more and pays attention to, and especially switched reluctance generator also receives attention gradually in the electricity generation field, but its current transformation system is as the core of switched reluctance generator system, develops comparatively slowly.
Each phase of winding is put into operation respectively according to the position relation between a stator and a rotor in the operation of the switched reluctance generator, the operation of each phase of winding is divided into two major phases of excitation and power generation and is carried out in a time-sharing mode, the excitation phase generally expects rapid excitation, because the excitation phase absorbs electric energy, the power generation phase outputs electric energy, the output electric energy in one period is necessarily larger than the absorbed electric energy, otherwise, the total output electric energy of the switched reluctance generator is negative, namely the generator is not available, and the excitation needs to establish current rapidly so as to reserve enough time and enough initial current for the power generation phase; meanwhile, the realization of the quick establishment of the exciting current under the rapid and intensified condition is often realized to be optimal under the simple structure and control.
In most application occasions, the voltage directly output by the generator often cannot meet the requirement, a separate device is further needed for boosting, the problem also exists in the field of switched reluctance generator systems, and the practical significance is achieved if the voltage jump is realized in both excitation and power generation conversion systems.
Because of the characteristic of inductive charging and discharging power generation of the winding of the switched reluctance generator, for the load side, the power supply (switched reluctance generator) is like a direct current source, so that in some occasions adopting the switched reluctance generator as an electric energy source in the industry, the switched reluctance generator is often a load which needs a relatively stable current source and needs higher voltage or a local area network, and therefore, the switched reluctance generator has practical significance if the original color of the direct current source output by the switched reluctance generator can be kept during voltage boosting.
The low voltage stress is a concern for various devices in the strong and weak current interface system in the power electronic industry, the high stress tends to bring about the complexity of structure and control, and the cost is increased, for example, in practice, one switch may need to be obtained by connecting a plurality of switch tubes in series and in parallel.
The switched reluctance generator system is common in a switched reluctance generator system with a storage battery serving as a separately excited power supply for power supply excitation, has the advantages of a separately excited mode, lacks the advantages of self excitation, and has the disadvantages of separate excitation, namely, the maintenance workload is increased, the charging of the storage battery by taking the generated voltage as input is a development trend, but faces the problems of adjustable automatic charging, decoupling from a power generation output end and the like as far as possible, and simultaneously, the charging is only required when the storage battery is required, so the utilization rate is too low after the charging system with a complex design is designed; by taking experience and reality in a double-fed asynchronous wind power generation system as reference, if a load side faces extreme conditions such as voltage sag, an original normal winding power generation output system cannot meet the requirement of the load side, and if a storage battery stores enough electric energy when electric energy output needs to be increased as soon as possible, can the storage battery be utilized? Especially, the battery charging system is used for reverse energy feedback operation? In addition, charging and energy feeding often work at high frequency, and because the driving of reducing volume, weight and cost is reduced besides improving the quality of electric energy, soft switching is often necessary, so that the efficiency and reliability are also improved.
