摘要
在电力系统中存在大量的非线性、波动性、冲击性负荷,这些负荷都会造成电能质量的下降。随着计算机和微处理器的发展,电力部门对电能质量监测越来越重要,尤其在对电能监测的电压、电流、频率等方面。要对电网的电能质量进行改善,通过借助微处理器STM32对电能质量做出精确的检测和分析。通过以太网对系统中电流可以实时监测,利用嵌入式系统μC/OS-II中TCP/IP协议作为通信方式,连接到上位机软件上,可以直观显示所监测数据,为进一步改善电能质量提供科学依据。
In the power system in the presence of large nonlinear, volatility and impact loads, the load cause the decline of the power quality. With the development of computers and microprocessors, power sector of the power quality monitoring is becoming more and more important, especiaUy in the power grid monitoring frequency, voltage and current. To the grid power quality improvement, it can use microprocessors STM32 for the electric power quality to make accurate detection and analysis. Through the Ethernet the system currents can be real time monitoring, the use of embedded system μ C/OS - Ⅱ TCP/IP protocol as a means of communication, connected to PC software, and visual display the monitoring data, in order to further improve the quality of power to provide the scientific basis.
