sequence switch

Firstly, by using the state jump function, we determine a strict increased switch-ing sequence for the system.

首先，通过状态跳转函数，确定系统一条严格递增的切换时间序列。

Through the structured modeling process, the whole control system is divided into several parts-input and output module, air compressor control module, sequence switch module, communication module, cylinder PID control module and alarm module.

该系统设计以项目要求为依据，通过结构化建模处理，将整个控制系统按功能划分为：输入输出模块，空压机控制模块，顺序切换模块，通讯模块，分气缸PID调节模块和报警模块。

To the power supply and logic circuits, apply some technique such as manostat, power-on sequence control and switch signal nesting, to ensure circuits stabilization, and play down the power dissipation of the module.

对于电源和时序控制电路，采取了电源稳压、加电顺序控制和收发切换时序嵌套等技术，来保证电路的稳定性，并尽量降低组件的电源消耗。

In order to greatly enhance the zero-sequence current active component during the single-phase ground fault, the short-time switch and the resistance paralleled with the petersen coil were controlled when there is a permanent single-phase ground fault in the system.

该方法当系统发生永久性单相接地故障时通过控制开关短时投切与消弧线圈并联的电阻，从而大大增强单相接地故障时的零序电流有功分量。
