摘要
为解决低压机电一体化配电网电力线载波通信过程中信噪比低、误码率高,影响通信稳定性问题,开展针对低压机电一体化配电网的电力线载波通信干扰频点过滤方法研究。通过电力线载波幅度调节、低压机电一体化配电网通信干扰频谱分解、载波通信时频峰值滤波、载波通信干扰频点扩频过滤,提出了一种全新的过滤方法。通过实例应用证明,新的过滤方法应用到真实配电网运行环境中,在不同信噪比条件下,通信误码率均低于通信质量标准规定的误码率0.6%,促进了低压机电一体化配电网整体运行质量提升。
In order to solve the problem of low signal-to-noise ratio and high bit error rate in the process of power line carrier communication of low-voltage electromechanical integration distribution network,which affects the stability of communication,the research on the frequency point filtering method of power line carrier communication interference in the low-voltage mechatronics distribution network is carried out.A new filtering method is proposed through power line carrier amplitude adjustment,communication interference spectrum decomposition of low-voltage mechatronics distribution network,carrier communication time-frequency peak filtering and carrier communication interference frequency point spread spectrum filtering.The application of examples shows that when the new filtering method is applied to the real distribution network operating environment,the bit error rates of communication are all lower than 0.6%stipulated in the communication quality standard under different signal-to-noise ratio conditions,which improves the overall operation quality of the low-voltage electromechanical integration distribution network.
