【摘要】：中国正处于一个蓝水海军快速发展时期,大型水面与水下战斗舰船正在研制与服役初期,各方面的配套设施需要完善,舰船的消磁系统就是其中之一。随着大型军用舰船的使用,消磁系统的功率越来越大,对消磁供电电源容量要求也在增加。本文利用超级电容贮能与电站共同形成脉冲放电电流,利用脉冲放电的间歇性特点,降低系统对电站功率的要求。首先,对贮能消磁模块组合电源的总体方案进行了详细设计。分析选取了消磁电源前级充电控制器和后级恒流变换器的拓扑形式。对消磁电流脉冲进行能量分析和计算,得出了四种不同工况下超级电容模组容量与需求供电功率的关系。其次,针对某个特定的电站供电功率,分别设计了后级变换器采用降压方式或升降压方式对应的电容模组分组方案和脉冲电流放电策略。并对两种方式下的前级充电机方案及后级变换器内部采用的并联路数进行了确定。进一步对两种方式下满足输出脉冲电流指标的后级变换器滤波电感、电容值进行了设计。再次,分别建立了单路Buck、单路Buck-boost以及多路交错并联的Buck、Buck-boost电路的平均状态空间数学模型。并以后级变换器采用降压方式为例设计了基于三环控制的最大电流均流法均流方案。最后,在Matlab/Simulink仿真环境下建立了后级变换器并联均流的仿真模型,并对后级变换器并联均流进行仿真和分析。同时也对后级变换器并联输出的脉冲电流能否满足精度、前后沿时间、超调量的要求进行具体分析。验证了基于三环控制的最大电流均流法在一相—重变换器并联运行以及在多相多重变换器并联运行中的均流有效性。
[Abstract]:China is in a period of rapid development of blue water navy. Large water surface and underwater combat ships are being developed and served in the early stage of service. The supporting facilities of various aspects need to be perfected. The demagnetization system of ships is one of them. With the use of large military ships, the power of the demagnetization system is becoming larger and larger, and the requirements for the capacity of the demagnetization power supply power supply are also in the same way. In this paper, we use the supercapacitor storage energy and the power station to form the pulse discharge current, and use the intermittent characteristics of the pulse discharge to reduce the power demand of the power station. First, the overall scheme of the combined power supply for the energy storage and demagnetization module is designed in detail. The pre stage charge controller and the rear constant current conversion of the demagnetization power supply are analyzed and selected. The energy analysis and calculation of the degaussing current pulse is carried out. The relationship between the capacity of the supercapacitor module and the power supply power is obtained under four different working conditions. Secondly, for a particular power station, the capacitor module grouping scheme corresponding to the depressurization mode or the lifting pressure mode is designed respectively for a certain power station power supply. And pulse current discharge strategy, and determine the number of parallel routes used in the front stage charger scheme and post stage converter in two ways. Further, the filter inductance and capacitance value of the post stage converter which satisfy the output pulse current index in two ways are designed. The single way Buck, single path Buck-boost are established respectively. And the average state space mathematical model of Buck and Buck-boost circuits with multiple interlaced parallel connections. And the post stage converter adopts the way of step-down as an example to design the maximum current mean current averaging scheme based on the three loop control. Finally, the simulation model of the parallel current sharing of the post stage converter is established under the Matlab/Simulink simulation environment, and the post stage transformation is transformed. The parallel current equalizing flow is simulated and analyzed. At the same time, the pulse current of the parallel output of the post stage converter can satisfy the precision, the requirements of the time and the overshoot are analyzed. It is verified that the maximum current mean current method based on the three loop control is parallel operation in a phase to heavy converter and the parallel operation of multiphase multiple converter. Flow efficiency.
