The power network detection information system based on gsm network is an intelligent product with computer technology , gsm mobile communication technology and signal processing technology , it can allow the real time detection of the voltage of the electricity transmission lines , can report the malfunction of the lines to the supervision center and the operators , and even can control relevant electricity equipments 基于gsm网络的电力网检测信息系统是集计算机技术、 gsm移动通信技术、信号处理技术于一体的智能产品,实现对电力网输电线路电压进行实时检测,向监控中心和工作人员报告线路故障,甚至输出开关量控制相应电力设备的功能。
The main contributions to the investigation of the device for fault location are as follows : a set of device for fault location of the transmission line is developed , which consists of the signal sensor and the data acquisition system . the data acquisition and calculation are controlled by industrial controlling computer 本文进行了高压架空线路故障测距装置的研究，设计制作了一台故障测距装置，设计了信号的传感器和数据采集部分，采用工控机控制数据采集卡进行数据采集和分析。
And to the electric capacity type voltage mutual inductor , because it compares with electromagnetic type voltage mutual inductor , transient state its bad to respond characteristic , as circuit when making the short circuit two times trouble , the voltage two times delays dropping to zero while needing to pass certain one 而对于电容式电压互感器，由于它与电磁式电压互感器相比，其瞬态响应特性比较差，当线路故障而使二次短路时，二次电压需经过一定的时延后才能下降到零。
In case of complicated dc circuit , any type of symmetrical ac system fault . dc line fault and dc line ' s recovery after fault can be more accurately simulated , and the dc line ' s dynamic response can be better represented . all the above is very important when doing the research on dc power support to ac system under emergency conditions , and has laid a solid foundation for the interaction study which will be met in a hybrid ac / dc power systems 该模型能够在对交流网络进行机电暂态计算的同时，对直流网络进行电磁暂态的计算，因而能较精确地考察暂态过程中直流线路的动态行为，并可对任意对称的交流系统故障、直流线路故障以及故障后直流输电系统的恢复等过程进行仿真，且仿真时间较短，为在复杂系统中研究直流输电系统与交流输电系统间的相互作用奠定了基础。
