摘要
近年出现的无线测温系统在开关柜测温领域中得到了良好运用,但因其普遍采用轮询方式进行无线组网,出现了监测节点数量较多时效率低下、功耗较大的问题。文中提出采用时分多址通讯技术进行无线组网,对系统进行分时处理,使系统按照严格的时序进行工作,提高了通讯效率;以IEC61850标准为基础进行系统结构设计,使通讯体系与智能变电站更兼容,符合智能电网要求;针对母排上供电困难的现状,系统进行了低功耗设计并以高容量电池为例进行了功耗分析,结果表明电池可以可靠工作2年以上,可使电池免于频繁更换,保证系统运行安全可靠性。
The temperature measurement using wireless measurement system in switchgear becomes more and more popular in recent years , but most of them adopt polling method to build the wireless network which makes the meas-urement system with low efficiency and high power consumption .The TDMA technology is proposed in this paper with the characteristics of time-sharing processing and working on time series strictly , which will improve the efficiency of measurement system .In order to meet the requirement of smart grid , the configuration of the wireless temperature measurement system is designed based on the standard of IEC 61850 and the communication system is fully compatible with the data transmission standard of new generation substation .Low power consumption technology is applied to solve the difficult problem-power supply .Taking the high capacity battery as example , the power consumption of the wireless temperature measurement system is calculated .The results show that the battery used in the measurement sys-tem has the lifespan of more than 2 years, which ensures the measurement system can work reliably for a long time .
