根据设计任务书的要求，本次设计为110kV 变电站电气一次部分初步设计，并绘 制电气主接线图及其他图纸。该变电站设有两台主变压器，站内主接线分为110kV、 35kV 和10kV 三个电压等级。各个电压等级分别采用单母线分段接线、单母线分段带 旁母接线和单母线分段接线(From the guide of engineering design assignment, we have to design primary power-system of 110kV substation and draw main electrical one-line diagram and others. There are two main transformer in the substation in which main electrical connection can be divided into three voltage grades: 110kV, 35kV with 10kV.It deposits sectionalized single bus bar scheme, sectionalized single and transfer bus bar and sectionalized single bus bar scheme per grade.)

说明：  基于MODBUS协议的单片机通信系统，上位机+下位机(MODBUS Protocol-based communication system microcontroller)

This is a generic FIFO buffer that can be used to store any kind of items. It is written in C language and can be compiled and used on almost any architecture. It was designed to be used on memory limited architectures such as microcontrollers. Examples of the applications that can be built with this library include:
