Description
Technical field
The present invention relates to the electric vehicles all when vehicle-used inverter generation power supply fault, fault of converter and motor body fault with fault-tolerant ability and open winding inverter circuit, be specifically related to a kind of electric vehicles duplicate supply five and open winding system failure tolerant method mutually.
Background technology
Automobile industry is the important component part of national economy, plays great function in national economy and social development.Along with the accelerated development of China's economy and the rapid raising of living standards of the people, automobile industry also will fast development, from now on longer one period automobile demand amount will keep strong growth.On the other hand, the problems such as the energy shortage brought by automobile industry and environmental pollution will be more outstanding, and tradition uses the development of automobile industry of internal combustion engine to have difficulty in taking a step.Therefore, accelerate to advance and develop energy-saving automobile and new-energy automobile, being effectively alleviate the energy and ambient pressure, the urgent task of propelling vehicle industry sustainable development, is also accelerate automobile industry transition and upgrade, tap new sources of economic growth and the strategic measure of international competitive advantage.
Fault tolerant permanent magnet machine not only has the advantage that magneto power density is high, output performance is good, also possesses motor body and the open circuit of controller, the strong fault tolerance ability of short trouble, has become the study hotspot in power drive field used for electric vehicle.Multi-phase motor system is compared with traditional three-phase system, and tool has the following advantages: (1), at power device voltage or the restricted special occasions of current class, can realize high-power driving; (2) because number of motor phases increases, the reliability of system is improved; (3) because number of motor phases increases, compared to three-phase system, the output machine torque pulsation of polyphase machine reduces, thus improves the performance of system; (4) electric system becomes five from three dimension system and maintains system, and the increase of dimension can make the control strategy of motor abundanter.In view of above-mentioned advantage, multiphase fault-tolerant electric system is made to have important application in occasions such as Aero-Space, boats and ships navigation, electric automobiles.
In traditional driving system of permanent magnet motor, the star-like connection in motor stator winding one end, the other end is connected with inverter.The asynchronous machine stator winding that Japanese scholars Isao Takahashi proposed in 1989 first by triangle connects is taken apart, winding six end lead-in wire is connected to two three-phase inverters respectively, form a kind of novel motor topology structure---drive winding asynchronous motor, as shown in Figure 1.Be compared to traditional driving system of permanent magnet motor, the neutral point of armature winding switching is taken apart, motor is made to present out winding construction, and the intrinsic Magnetic circuit characters of motor can not change, motor still has the advantage such as high power density, high efficiency, also meets the needs of electric automobile motor drive system fault-tolerant operation simultaneously.When motor driven systems breaks down, the electric current of fault phase or busbar voltage can not have influence on other normal phase windings, effectively eliminate the impact between winding, improve motor own reliability.Make motor driven systems control more flexible, circuit topology is more suitable for faults-tolerant control, can realize the uninterrupted operation of electric automobile, improves the reliability of motor driven systems simultaneously.
Motor driven systems forms primarily of motor body, inverter, controller and sensor part, the safety and steady that its reliability is directly connected to whole system runs, the fault of any part all likely has influence on the normal work of whole system, even causes the generation of systemic breakdown and security incident.The power supply of electric vehicles drive system is requisite part in system, and it is in running, crosses the situations such as cause thermal damage be easy to cause power failure due to overcurrent, overvoltage and components and parts.Inverter is the most frequently used power conversion unit, and device for power switching is due to outside being often exposed to, and the operating state of high frequency makes that loss is comparatively large, heating is serious, and its fragility makes switching tube faults frequent occur.In addition, automobile motor internal stator fault is also multiple fault, as: the single-phase open circuit fault of stator winding, shorted-turn fault, stator winding shorted to earth and stator winding phase fault.The generation of above-mentioned fault gently then causes system-down to affect vehicle operating, heavy then cause immeasurable seriousness economic consequences and casualties.
This patent considers the various fault types that said system may occur, in conjunction with the simple switching with control strategy that improves and optimizates of inverter topology, make the generation of Arbitrary Fault all can realize topology reconstruction and first fault-tolerant uninterrupted operation carries out fault detect to motor driven systems after system jam, again defective device is isolated, then utilize this electric vehicles to open winding inverter fault tolerable circuit and carry out topology reconstruction and control algolithm switching, keep the lasting uninterrupted operation of whole system.
Summary of the invention
For the research of conventional electric automobile driving system failure tolerant, be generally adopt circuit redundant technique and topology reconstruction to realize System Fault Tolerance.But the redundant technique of circuit is often realize system by the configuration of stand-by circuit to run without interruption, and easily causes circuit devcie use cost to increase, the wasting of resources; Inverter topology reconstruct realizes System Fault Tolerance by the structural remodeling during health in primary circuit and runs, though do not increase hardware cost, the faults-tolerant control strategy of motor is complicated and changeable.In addition, in existing drive system of electric automobile failure tolerant research, all often carry out fault-tolerance study for a certain specific fault of system, and drive system of electric automobile operating condition is complicated, failure mode is various, so need launch the research of the Integrated Fault Tolerant strategy for motor driven systems various faults.
