Abstract

It is shown that, to calculate the installed capacity of a network storage device for drilling rig objects, it is necessary to build a load graph—the dependence of the supply network voltage as a function of time. This graph can be calculated on the basis of statistical data of possible and permissible voltage dips in time and depth. The proposed structure of the network drive can work as a part of both diesel-generator and gas-piston installations. The structure of the network storage of electric energy is presented using an example that contains the following enlarged nodes: cabinets with switching equipment, network-filter cabinets, a cabinet of semiconductor active rectifiers, electric-energy storage devices based on supercapacitors and lithium batteries, and a microprocessor control cabinet. A structure of network energy-storage devices containing an active rectifier is proposed in which it becomes possible to adjust the power factor of the system by influencing the control signals on the active and reactive components of the currents. It is shown that the proposed drive allows one to maintain failure of supply voltage for 10 s, provided that an installed power of the drive is selected equal to half of the total power of the installation. The developed structure can be turned on in parallel with renewable energy sources, and can also be used as a fast charging station for electric vehicles.

网络储能创新解决方案

摘要

结果表明，要计算用于钻机对象的网络存储设备的装机容量，需要构建负载图——供电网络电压与时间的函数关系。该图可以根据时间和深度上可能和允许的电压骤降的统计数据计算得出。网络驱动器的提议结构可以作为柴油发电机和气体活塞装置的一部分工作。以包含以下放大节点的示例展示了电能网络存储的结构：带开关设备的柜、网络滤波器柜、半导体有源整流器柜、基于超级电容器和锂电池的电能存储装置、和微处理器控制柜。提出了一种包含有源整流器的网络储能设备结构，其中通过影响电流的有功和无功分量上的控制信号来调整系统的功率因数成为可能。结果表明，如果选择的驱动器安装功率等于安装总功率的一半，则建议的驱动器允许一个人将电源电压故障维持 10 秒。所开发的结构可与可再生能源并行开启，也可用作电动汽车的快速充电站。结果表明，如果选择的驱动器安装功率等于安装总功率的一半，则建议的驱动器允许一个人将电源电压故障维持 10 秒。所开发的结构可与可再生能源并行开启，也可用作电动汽车的快速充电站。结果表明，如果选择的驱动器安装功率等于安装总功率的一半，则建议的驱动器允许一个人将电源电压故障维持 10 秒。所开发的结构可与可再生能源并行开启，也可用作电动汽车的快速充电站。
