摘要
由于在配电系统的环形供电网络中供电线路分散性大,使得电缆、光缆的有线通讯方式投资大、可靠性低,该文提出并研制了基于GPRS(通用分组无线业务)网络的新型环网柜终端,该终端以DSP为核心,对配电环网中的电压、电流、三相总的有功电量、无功电量以及环网柜电缆出线故障进行监测,是集环网柜终端、电能表、无功补偿装置为一体的新型设备。通过GPRS网络为信道传输数据,实时性好、可靠性高、投资小。
The distribution of the urban power distribution network lead to incredible amount of investment and poor credibility of the communication by means of coaxial cable and optical cable. To solve this problem, a new type of advanced switchgear cubicle based on GPRS network is developed. The central part of the terminal is DSP. The voltage, current, active power, reactive power and the fault of the power cable of three phase can be monitored. It is the equipment that comprise switchgear cubicle, power meter and SVC. It takes the GPRS network as its communication channel with the advantage of real-time, high reliability and low cost.
