Description
Translated fromChinese本发明涉及电力领域，具体涉及一种基于无人机斜拉法的特高压线路人工短路试验方法。The invention relates to the field of electric power, in particular to an artificial short-circuit test method for ultra-high voltage lines based on a UAV cable-pull method.
高压并联电容器组作为无功补偿设备被广泛应用于变电站中，用来提高负荷的功率因素、改善电压质量、减少网损及增加系统电压稳定性等。放电线圈用于电力系统中与高压并联电容器连接，使电容器组从电力系统中切除后的剩余电荷迅速泄放。安装放电线圈是变电站内并联电容器的必要技术安全措施，可以有效的防止电容器组再次合闸时，由于电容器仍带有电荷而产生危及设备安全的合闸过电压和过电流，并确保检修人员的安全。因此，保障高压并联电容器组放电线圈稳定安全运行至关重要。High-voltage shunt capacitor banks are widely used in substations as reactive power compensation equipment to improve the power factor of loads, improve voltage quality, reduce network losses and increase system voltage stability. The discharge coil is used to connect with high-voltage parallel capacitors in the power system, so that the residual charge after the capacitor bank is removed from the power system is quickly discharged. The installation of the discharge coil is a necessary technical safety measure for the parallel capacitors in the substation, which can effectively prevent the closing overvoltage and overcurrent that endanger the safety of the equipment when the capacitor bank is closed again, because the capacitor still has electric charge, and ensure the safety of the maintenance personnel. Safety. Therefore, it is very important to ensure the stable and safe operation of the discharge coil of the high-voltage parallel capacitor bank.
10kV电容器的放电线圈二次侧额定电压一般为100V。在电容器停电时，放电线圈作为一个放电负荷，会快速泄放电容器两端的残余电荷，以满足电容器5min内5次自动投切的需要。标准要求退出的电容器在5秒钟之内其端电压要小于50V。The rated voltage of the secondary side of the discharge coil of a 10kV capacitor is generally 100V. When the capacitor is powered off, the discharge coil, as a discharge load, will quickly discharge the residual charge at both ends of the capacitor to meet the needs of automatic switching of the capacitor 5 times within 5 minutes. The standard requires that the terminal voltage of the withdrawn capacitor should be less than 50V within 5 seconds.
目前，放电线圈的检修主要采用故障检修方法和定期检修方法。故障维修方法是当放电线圈已经出现故障不能再运行时，导致供电运行中断后才采取的检修方式，在这之前已经遭到了一定程度的破坏，维修代价很大而且非常危险。定期检修方法是当放电线圈运行一段时间之后，进行一次全方位的检修，从而保证了其稳定运行。但随着供电设备不断增加，供电方式也不断多样化，这种检修方法已经显得有些力不从心，缺陷也日益凸显。At present, the maintenance of the discharge coil mainly adopts the fault maintenance method and the regular maintenance method. The fault maintenance method is the maintenance method that is adopted after the power supply operation is interrupted when the discharge coil has failed and can no longer be operated. Before that, it has been damaged to a certain extent, and the maintenance cost is very high and very dangerous. The regular maintenance method is to carry out an all-round maintenance after the discharge coil has been running for a period of time, thus ensuring its stable operation. However, with the continuous increase of power supply equipment and the continuous diversification of power supply methods, this maintenance method has become somewhat inadequate, and its defects have become increasingly prominent.
随着直流输电技术的发展和我国直流输电设计、制造的自主化进程，目前我国已经建成并投产了多条特高压直流输电工程，最大传输功率达到8000MW，最远传输距离可达3000多公里。With the development of HVDC transmission technology and the process of independent design and manufacture of HVDC transmission in my country, my country has built and put into operation a number of UHVDC transmission projects, with a maximum transmission power of 8,000MW and a maximum transmission distance of more than 3,000 kilometers.
在直流工程系统建成之后，系统投运之前，需要对整个系统进行调试测试。这是验证高压直流输电工程建设是否达到了设计标准的关键一步。只有完全通过调试测试各项目要求，并完全排除可疑故障的直流系统方可投入运行。After the DC engineering system is built and before the system is put into operation, the entire system needs to be debugged and tested. This is a key step to verify whether the HVDC project construction meets the design standards. Only the DC system that has completely passed the commissioning and testing requirements of each item and completely eliminated suspicious faults can be put into operation.
人工短路接地试验是在高压输电工程调试期间需要进行的一项试验，其目的是检查相应设备及保护的动作行为、动作时间是否满足工程设计要求，符合竣工投运要求。在特高压直流输电线路中，人工接地短路试验还可以检查系统的故障自清除能力，考验系统的稳定性。The artificial short-circuit grounding test is a test that needs to be carried out during the commissioning of the high-voltage power transmission project. In UHVDC transmission lines, the artificial grounding short-circuit test can also check the fault self-clearing ability of the system and test the stability of the system.
由于在人工接地短路试验的过程中，短路接地点将会通过巨大的电流，使得接地点附近产生很大的跨步电压，周围的操作人员具有一定的安全风险，引弧线产生的瞬间高温还可能引燃周围的草木。传统的人工接地短路试验的方法是用弓弩发射连接引弧线的箭矢进行短路。这种方法容易受到天气因素影响，对地形有一定的要求，且存在失误率高、试射浪费箭支等问题。During the artificial grounding short-circuit test, a huge current will pass through the short-circuit grounding point, resulting in a large step voltage near the grounding point, and the surrounding operators have certain safety risks. May ignite surrounding vegetation. The traditional method of artificial grounding short-circuit test is to use a crossbow to fire arrows connected to the arc-starting line to short-circuit. This method is easily affected by weather factors, has certain requirements on terrain, and has problems such as high error rate and waste of arrows in test shooting.
