摘要
高压电力传输线路的监视控制、故障检测、故障定位对于保证电网的安全运行有着重要的意义。采用高精度三相电能专用计量芯片ATT7022A和低功耗、强抗干扰的STC89C516RD+单片机,开发高压电力线路监控终端硬件系统,可以完成电力参数及时、准确地检测和报警。同时系统具有灵活的远程软件校表功能。现场运行表明,系统稳定可靠,具有较高的实用价值。
SCADA, fault detection and fault location of high voltage electric power transmission can guarantee electric power network running safely. It is proposed in this paper that using high precision three-phase energy metering IC ATI7022A and low power, high anti-jamming MCU STC89C516RD ＋ design termainal SCADA hardware system of electric power. This system can detect electric power parameters and alarm in time and exactly. And this design has an advantage that is agile and remote software regulating meter. The field experiments have proved this svstem can work stably and reliably and has high practical value.
