摘要
针对煤矿井下用电负荷特征,提出在煤矿井下探索采用直流供配电系统,并从供电容量和供电距离两方面分析说明其合理性。针对直流供电在节能、建造及运行成本低、线路损耗小且易于扩展容量等诸多优点,已成为电力系统领域研究热点。基于目前研究处于低压直流开关电源,结合煤矿供电网络和用电设备特点,初步提出煤矿直流配电网络拓扑和中高压直流输电的电力电子变压器拓扑,分析构建煤矿直流供电系统涉及的关键技术,并对煤矿分步实施直流供电网可行性进行了分析和展望。
Aiming at the characteristics of underground power load in coal mine, the author proposed to explore the use of DC power supply and distribution system in coal mine underground. For the advantages of low energy saving, low construction and operation cost, low line loss and easy expansion capacity, DC power supply has become a hot spot in power system research. Based on the current research on low-voltage DC switching power supply, combined with the characteristics of coal mine power supply networks and power equipment, the topology of coal mine DC distribution networks and the power electronic.Transformer topology of medium-high voltage DC transmission are initially proposed, and the key technologies involved in the construction of coal mine DC power supply systems are analyzed. The feasibility of implementing DC power grid in coal mine is analyzed and forecasted.
