客户侧窃电行为不仅造成电能资源大量流失,同时造成线路负荷过载引发火灾等重大安全事故.针对当前客户侧窃电行为的多样性与隐蔽性特征,以约束客户侧窃电行为为目的 ,设计了客户侧窃电态势感知及智能预警关键技术.考虑客户侧窃电行为的多样性与隐蔽性特性,选取额定电压偏离度、电压不平衡率与电流不平衡率等6个客户侧窃电态势感知指标,利用RBF神经网络构建客户侧窃电态势感知模型,将所选取的6个指标与相关数据作为模型输入,通过动态K均值聚类算法优化模型,模型输出结果即为客户侧窃电态势感知结果.基于感知结果,通过声光报警装置与智能设备实现智能预警,实验结果显示,该技术能够有效抑制客户侧窃电行为.

为解决传统的"拉网式排查"工作方式存在判定窃电行为依赖个人经验、效率不高、跑冒滴漏多等不足,难以适应不法分子窃电向专业化、隐蔽化、职业化发展的趋势,提出了建设智能反窃电信息平台的思想.该平台通过对用电信息采集系统原始数据的挖掘和分析,应用窃电指纹库的模型和算法,对异常用电情况进行检查、取证、分析和处理;通过建立统一的智能反窃电信息平台,提升供电公司反窃电信息技术水平,将供电公司的用电检查与反窃电工作推向信息化、自动化、智能化

我国西南地区的电力线路检查工作工中存在着人工检查耗时耗力、地形地貌复杂的特点。为解决此类问题，电力企业引进了航拍技术。无人机航拍技术与传统的人工检查相比，无人机航拍检查技术具有低成本、全天候、适应复杂地形的优势，能够帮助电力运维检修单位及时获取图像信息，对于提升工作效率、降低劳动强度具有重要意义。本文主要针对无人机航拍技术，结合电力企业线路检查的实际情况，对无人机在其中的应用进行分析，以期更好改进我国的电力系统检查维护水平。

目前窃电现象严重且窃电手段先进,但反窃电手段仍以人工稽核为主,存在工作量大、取证困难和缺乏针对性等问题.为了解决上述问题,利用供电企业积累的大量客户档案数据和历史用电数据,通过二阶聚类分析窃电用户的定性特征,用深度学习和CHAID决策树分类评估用户的窃电嫌疑概率,根据异常值分析手段为疑似窃电行为取证提供依据.实践表明,本方案缩小了窃电嫌疑用户范围,减少了防窃电的工作量,提高了稽核针对性,且为供电单位进行窃电侦查提供了依据,从而减少了供电企业财务损失,保障电网运行安全.

The management of KPI has been valued a lot in modern business management.Based on the features of the marketing management in power supply enterprises,this essay presents the principles and approaches of the design of KPI as well as proving its superiority from its application in Chongqing Electric Power Corporation.

The method of closed-loop obstacle avoidance of the location for mobile robot based on the virtual force field was proposed.This method,which is simple and intuitive,permits the mobile robot to detect unknown obstacles and avoid collisions in the movement and further advance toward the target.Experiments show the good effect of this method

According to the actual situation between power supply companies and customers,this paper puts forward strategies for recovery of electric charge under the financial crisis,and introduces some innovative measures,such as the third-party security guarantee,and many kinds of legal means to ensure recovery of electric charge.

To satisfy various demands of information integration in the customer field management system,Web Services technology is adopted to integrate the real-time data and FTP(file transfer protocol) to transfer formatted files for non-real-time data integration.By the two integration methods the following functions have been realized:basic document information synchronization,automation of services such as meter reading and fee reminding,as well as comprehensive monitoring of important customers.Recently,the two methods have both been applied in the business integration of the customer field management system and the marketing management system in Chongqing Electric Power Company.

The article makes full use of electronic multi-function watt-hour meter communications capabilities, combines with the existing radio channel resources and terminal equipment of the power load management system. It can realize remote automatic meter reading of professionals district users. Existing wireless meter reading technology is improved, and the 230 MHz frequency signal which can not be covered by or under the weak signal of the local is increased in simplex smart terminal communications in order to make up blackout and avoid the failure of the meter reading.

The embedded gateway system based field bus (CAN) was designed and fulfilled. As the hinge where the field bus and Internet exchange the data,it can enhance the eficiency of monitoring the electric power system
