Description
技术领域technical field
本发明涉及无线通信网络的技术领域，尤其涉及基于无线通信网络的电力系统保障装置。The invention relates to the technical field of wireless communication networks, in particular to a power system guarantee device based on wireless communication networks.
背景技术Background technique
变电站是电力系统中变换电压、接受和分配电能、控制电力的流向和调整电压的电力设施，它通过其变压器将各级电压的电网联系起来。为了把发电厂发出来的电能输送到较远的地方，必须把电压升高，变为高压电，到用户附近再按需要把电压降低，这种升降电压的工作靠变电站来完成。因此变电站在电网中起到至关重要的作用。为了保证变电站的正常运行，需要进行日常运维工作，这些运维工作通常依靠运维人员来完成。A substation is a power facility in the power system that transforms voltage, receives and distributes electric energy, controls the flow of power, and adjusts voltage. It connects the power grids of all levels of voltage through its transformers. In order to transmit the electric energy from the power plant to a distant place, the voltage must be raised to become high-voltage electricity, and then the voltage is lowered as needed near the user. This work of raising and lowering the voltage is done by the substation. Therefore, substations play a vital role in the power grid. In order to ensure the normal operation of the substation, daily operation and maintenance work is required, and these operation and maintenance tasks are usually completed by operation and maintenance personnel.
但是随着电网的不断发展，变电站越来越多，运维成本也越来越高，由于站点变多，运维人员在进行具体运行过程中也只能优先从当前距离较近的站点进行运维巡逻，同时在巡逻过程中也没有针对性的对故障率及隐患较大的变电站进行着重查看，运维效率及准确性不足。现有中也存有相应的运维路线优化方式，如授权公告号：CN112261385B——变电站远程运维系统及运维方法，该项技术也仅仅是针对整体路线远近来进行路线配置，未曾将故障率及隐患作为评判标准进行路线的进一步优化，不利于运维工作的深层次开展。However, with the continuous development of the power grid, there are more and more substations, and the operation and maintenance costs are also getting higher and higher. Due to the increase in the number of sites, the operation and maintenance personnel can only give priority to operating from the current shorter site during the specific operation process. At the same time, during the patrol process, there was no targeted inspection of substations with high failure rates and hidden dangers, and the efficiency and accuracy of operation and maintenance were insufficient. There is also a corresponding operation and maintenance route optimization method in the existing system, such as the authorization announcement number: CN112261385B - substation remote operation and maintenance system and operation and maintenance method, this technology is only for the overall route configuration, and has not eliminated the fault The further optimization of the route takes the rate and hidden dangers as the evaluation criteria, which is not conducive to the in-depth development of the operation and maintenance work.
