Real-Time Acquisition Method of Weak Signal of Distribution Network Terminal Equipment Operation Based on LMS Algorithm
摘要
The current distribution network weak signal real-time acquisition node is multiset as the target form, and the acquisition range is greatly limited, resulting in the increase of the final acquisition single point error. Therefore, this paper proposes the design and verification analysis of the LMS algorithm-based distribution network terminal equipment operation weak signal real-time acquisition method. According to the signal acquisition requirements and standards, extract the initial characteristics of signal acquisition, expand the signal acquisition range in the form of multi-target, set multi-target acquisition nodes, and establish a single-end device signal acquisition matrix. Based on this, build a real-time acquisition model for LMS accounting weak signals, and complete real-time acquisition by using compressed signal sensing processing. The final test results show that through three measurements, the single point error of the real-time signal acquisition of the distribution network equipment is better controlled below 0.2, indicating that this method has better signal acquisition speed and efficiency, larger acquisition range, more rigorous comparison, and more controllable error, which has practical application value.
