电力线路无线核相方法研究
摘 要
随着我国实施碳达峰和碳中和政策，我国在全球范围内的利用日益增多。为实现清洁能源的合理输送和分配，以及解决我国洁净资源的非平衡性，我国特高压、超高压电网的工程正在进行中。由于电网的产品、营销等各方面都具有其自身的特点，使得电网的相位核对从单机到多台，使得相位校验的复杂程度和频率越来越高，这就给相位校验带来了新的挑战，如何快速准确地校验相位是保证电网的供电质量的关键。基于这一点，本文研究了远距离不同电压等级的输电和输电线路的无线核相法。
首先，分析了远距离无线核相技术的原理与技术。其次，基于同网同频的特点，提出了一种基于软件和软件的非同步核相位技术，在系统的硬件方面，从经济和实用两方面对各模块进行了详细的分析。在此基础上，对该方案进行了软体和软体的检测，并对无线传输、电磁干扰等因素的影响进行了研究。实验证明，采用该方法可以实现对输电、配电系统的相位核测量。此方案具有造价低、能耗低、能在较短的时间内实现远端、远端的不同电压等级间的功率核相，极大地减少了作业中的危险性和工作量，满足了实际的维修和运营需求，达到了预定的目的。

Abstract
With the implementation of carbon peaking and carbon neutrality policies in China, China's utilization in the world is increasing. In order to realize the reasonable transmission and distribution of clean energy and solve the imbalance of clean resources in China, the construction of UHV and UHV power grids in China is under way. Because the products and marketing of the power grid have their own characteristics, making the phase check of the power grid from single to multiple, making the complexity and frequency of the phase check increasingly high, which brings new challenges to the phase check. How to quickly and accurately verify the phase is the key to ensure the power supply quality of the power grid. Based on this point, this paper studies the wireless core phase method for long-distance transmission and transmission lines with different voltage levels.
Firstly, the principle and technology of remote wireless phase core technology are analyzed. Secondly, based on the characteristics of the same network and the same frequency, a non-synchronous core phase technology based on software and software is proposed. In terms of the hardware of the system, the economic and practical aspects of each module are analyzed in detail. On this basis, the software and software of the scheme are tested, and the effects of wireless transmission, electromagnetic interference and other factors are studied. Experiments show that the phase kernel measurement of transmission and distribution systems can be realized by using this method. This scheme has the advantages of low cost, low energy consumption, and can realize the power core phase between remote and remote voltage levels in a short time, greatly reducing the risk and workload in operation, meeting the actual maintenance and operation requirements, and achieving the intended purpose.
