The conditions of building and its environment can make the series-wound or shunt-wound photovoltaic modules have some difference.

建筑及其环境的原因可造成串、并联在起的同样的光伏电池组件形成不同的输出功率。

Separation Model: Series-wound mode, parallel-plane symmetry mode and parallel-axial symmetry mode are defined to form Separation Model;

级间分离段模型：建立面对称并联式分离、轴对称并联分离和串联式分离；

The part of timing is a double closed loop DC timing system, and it is composed of rev loop (internal loop) and current loop (external), which are series-wound.

调速部分为双闭环直流调速系统，由转速环(内环)和电流环(外环)串联组成。

The 6kv transducer with the series-wound unit of the PWM pressure type can realize the output of the direct high pressure by collecting a lot of lower frequency conversion pressure.

单元串联多电平pwm电压源型6 k V变频器采用若干个低压PW M变频功率单元串联的方式实现直接高压输出。

The result shows that, in series-wound mode, the distance between the two stages changes fast, the time of reaching safety distance is short, and the probability of side-collision is little.

仿真结果表明，串联方式相对距离变化快，达到安全距离耗时短，侧向碰撞几率小；
