【摘要】 简述了电能质量的重要性以及电能质量监测系统的发展方向。结合某钢铁厂已建立的信息局域网络,根据已有的电能质量监测设备,给出了该钢铁厂的网络型电能质量监测系统监测终端的构建方案。采用DSP加工控机的主从式结构,对重点监测数据选择了合适的计算方法,以实现数据采集、数据初步分析和数据传输等功能。更多还原

【Abstract】 The importance of power quality and the development trend of power quality monitoring system are introduced briefly. Combining with the local area infornlation network established by a steel plant,based on the existing power quality monitoring device, a construction scheme for monitoring terminal of web-based power quality monitoring system is provided.In this scheme,a host- hypotaxis structure that includes DSP and industrial control computer is adopted; for the important monitoring data,the appropriate calculation method is selected to realize the functions of data’s acquisition,preliminary analysis and transmission.更多还原
