Research on safety monitoring in active sensor in power system

针对电力系统高次谐波的安全检测需求,提出主动式传感器在电力系统中的安全检测方法,构建安全检测模型。模型采集电力设备用电数据以及用户用电数据,通过电力设备监控器、主动式传感器和网络分析器,检测出电力系统标准作业和协同作业场景中的非善意入侵动作。以主动式传感器进行的高次谐波检测为主,提出正序谐波、负序谐波和零序谐波的即时检测方法,将电力设备数据更替为三相电压矢量,使用主动式传感器将矢量电流转换成即时电流。实验结果说明,所提方法的运算消费和通讯消费低,能量消耗小。

In view of the demand for the safety detection power system security detection method, safety test model was of higher harmonic in power system, put forward the active sensor in the constructed. Model of electric power equipment electricity utilization data and user data, through the power equipment monitor, active sensor and network analyzer, detect the power system standard work and work together in the scene than the invasion of good faith actions. With active sensor for high order harmonic detection is given priority to, put forward positive sequence harmonic, negative sequence and harmonic zero sequence real- time detection method of harmonic power equipment data for three-phase voltage vector, using active sensor will be converted to vector current instantaneous current. Experimental results indicate that the proposed method of computing and communication consumption is low, energy consumption is small.
