提高连续供电的质量,降低设备运行费用的措施之一是建立一个两级结构的电网,即主环网向二级环网供电,由二级环网连接MV/LV 变压器。配电设备的安全与可靠性直接影响配电网络的稳定性。
RM6 新扩展系列是施耐德电气公司在RM6 和RM6 可扩展系列产品基础上推出的新型模块,包括计量,母联,电缆进线,双进扩展柜等。它做为RM6 产品的必不可少的一部分,不但延续了其做为SF6 绝缘全密封设备在环境适应性方面的特点,而且增强了其在紧凑性和模块化方面的应用。
RM6 新扩展系列提供了几种重要的功能模块,结合RM6 可扩展系列的功能单元后特别适用于二级环网,包括:
·b 供电局所属变电站
·工矿企业所属变电站
·民用所属变电站
RM6 新扩展系列产品,可以用于MV/MV 二次开关站和MV/LV 变电站及工矿配电站,以满足中国二次变电站的各种特殊的技术要求。
LC and other subsystems communicate with industrial “system through Modbus protocol interface. The system also supports iec870-5 over control coordination
Discussion.
The flash EPROM inside PS provides more than 220 function modules (control algorithm subroutines), in addition to the base specified in IEC 61131 3 standard
In addition to this content, many powerful and strictly tested function blocks from practical engineering applications are also expanded. Any complex control
All schemes can be realized by the combination of these function blocks.
The function blocks provided by the system mainly fall into the following categories:
o
Analog quantity processing
o
Digital quantity processing
Loop adjustment
Logical sequence control
c
Logical operation
Monitoring function
Acquisition function
c
Arithmetic operation
c
Tcp/ip protocol communication interface
Modbus protocol communication interface
1ec870-5 protocol communication interface (telecontrol)
4.2 field controller PS
Industrial ial “field controller PS is a special process control station, which is embedded with a fieldbus communication interface for users to use
