摘要
研究了一种蓄电池供电系统的设计方案。介绍了其整体结构工作原理、工作模式及控制约束。该设计实现了蓄电池充电、并网与功率调节一体化的控制集成。基于广义功角特性,提出了一种对逆变器输出功率进行直接控制的方法,通过三绕组变压器实现控制功率传输方向和大小。该控制规律对直流储能装置的参数具有很强的鲁棒性,因而该控制器能适应各种不同参数的蓄电池、太阳能电池板等,成为蓄电池供电系统与功率调节的独立装置。
The design of a battery power supply system was studied.The principle,mode and control constraints of overall structure were introduced.An integrated control system of charging battery/grid-connected and power regulation was achieved.Based on generalized power angle characteristics,a new control scheme was proposed to control the output power of the inverter directly to realize adjusting the direction and size of the power transmission.The proposed control law is robust to the DC energy storage device.So the integrated controller is thus applicable to different battery/ solar panels,etc,in fact it is a separate device for battery power supply system and regulating active power.
