摘要：

详细的用户用电信息是推进节能减排、实施能源优化的关键。针对在获取精确的用电信息过程中存在的电力线干扰问题,文中提出了一种基于用电标识的新型用电量计量系统。该计量系统由用电标识端与采集计量端两部分组成。用电标识端通过ASK(Amplitude Shift Keying)数字调制为各用电器的用电信息进行独立编码,经电容耦合至电力线。采集计量端通过电力线载波通信对独立编码信息进行采集,并分析处理从而实现用电量计量。通过Multisim与MATLAB仿真软件对所提计量方案进行仿真验证,根据用电器特性可独立编码用电信息,采集计量端通过对独立编码数据分析处理可还原用电器的用电特性波形,实现较好的抗干扰性。

Abstract:

The detailed user's electricity consumption information is the key to promote energy conservation and emission reduction, and implement energy optimization. In view of the problem of power line interference in the process of obtaining accurate electricity consumption information, a new electricity consumption metering system based on electricity consumption identification is proposed in this study. This metering system is composed of two parts: the electricity identification terminal and the collection and metering terminal. The electrical identification terminal is digitally modulated by ASK(Amplitude Shift Keying) to independently encode the electrical information of each electrical appliance, and is capacitatively coupled to the power line. The acquisition and metering terminal collects independent coded information through power line carrier communication, and analyzes and processes it to realize electricity consumption measurement. The metering scheme is simulated and verified by Multisim and MATLAB simulation software. According to the characteristics of electrical appliances, the electricity information can be encoded independently, and the acquisition and metering side can restore the waveform of electrical appliances by analyzing the independent coding data to achieve better anti-interference.

Key words: electricity consumption identification, ASK, independent encoding, electricity metering, harmonic interference, power line carrier communication, FFT, harmonic analysis
