摘　　要：介绍了一种基于GPS高精度全网统一时钟的稳态相角测量的硬件方案。该设计采用模块化结构,由两个(或多个)过零点时标生成模块和一个中心处理模块组成,利用过零点时标生成模块为电压过零点打上精确的时间标签,并上传到调度中心,由中心处理模块对上传的一系列时间信息进行处理,计算出电压的稳态相角。可与目前的调度自动化系统配合使用实现电力系统的稳态相量可观,具有安装和调试方便、传输信息量小、速度快、抗干扰强、测量准确等优点。The technical method is introduced in this paper for the steady state phase angle measurement and the research aspects in applications based on GPS. In the design of this unit, a modularized method is adopted, which by the two （or more） measurement modules and a control module. The zero-crossing is marked on time label by measurement module. The time label is transferred to dispatching centers. Control module disposes data and calculates the steady state phase angle. This design and SCADA can be used in conjunction with,to achieve the steady-state phasor of the power system can be observed.It has the advantages of easy installation and debugging ,small amount of information, high-speed transmission, anti-interference measures and accurate measurement.
