However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. These embodiments are provided so that this disclosure will be thorough and complete. invention, and fully convey the scope of the invention to those skilled in the art. The terminology used in the exemplary embodiments represented in the drawings does not limit the invention. In the drawings, identical units/elements use the same reference numerals.
除非另有说明，此处使用的术语(包括科技术语)对所属技术领域的技术人员具有通常的理解含义。另外，可以理解的是，以通常使用的词典限定的术语，应当被理解为与其相关领域的语境具有一致的含义，而不应该被理解为理想化的或过于正式的意义。Unless otherwise defined, the terms (including scientific and technical terms) used herein have the commonly understood meaning to one of ordinary skill in the art. In addition, it is understood that terms defined in commonly used dictionaries should be understood to have consistent meanings in the context of their relevant fields and should not be understood as having an idealized or overly formal meaning.
架空输电线路由线路杆塔(又称输电杆塔或输电铁塔)、导线、绝缘子、线路金具、拉线、杆塔基础、接地装置等构成，架设在地面之上。Overhead transmission lines are composed of line towers (also known as transmission poles or transmission towers), wires, insulators, line fittings, guy wires, tower foundations, grounding devices, etc., and are erected above the ground.
档距：架空输电线路在平行于相邻两杆塔间导线所受比载的平面内的两悬挂点之间的水平距离，为这两基杆塔的档距。Spacing: The horizontal distance between two suspension points of an overhead transmission line in a plane parallel to the specific load of the conductors between two adjacent towers is the spacing of the two base towers.
线路走廊：架空输电线路的路径所占用的土地面积和空间区域。为了保证线路绝缘强度和避免对人身及地面建筑等物体的触电危险，以及防止静电场对导线及附近的人造成生理和生态危害，处于高电压下的导线周围，需保持必要的净空间区域。随着输电线路电压等级的提高，线路走廊的范围显著扩大。例如,单回500千伏超高压输电线路，杆塔高度一般均达30米，线路走廊宽度约达45米。Line Corridor: The area of land and space occupied by the path of an overhead transmission line. In order to ensure the insulation strength of the lines and avoid the risk of electric shock to people and ground buildings, as well as to prevent the electrostatic field from causing physiological and ecological harm to the wires and nearby people, a necessary clear space area needs to be maintained around the wires under high voltage. As the voltage levels of transmission lines increase, the extent of line corridors expands significantly. For example, for single-circuit 500 kV ultra-high voltage transmission lines, the height of the tower is generally 30 meters, and the width of the line corridor is about 45 meters.
分裂导线指超高压输电线路为抑制电晕放电和减少线路电抗所采取的一种导线架设方式，每相导线由几根直径较小的分导线组成，各分导线间隔一定距离并按对称多角形排列，而且布置在正多边形的顶点上。分裂导线相比总截面相同的大导线，不容易产生电晕，送电能力还高一些。分裂导线主要有应用于220千伏及以上电压的线路上。一般是220kV为2分裂，500kV为4分裂，西北电网750kV为6分裂，1000kV为8分裂。Split conductor refers to a conductor erection method adopted by ultra-high voltage transmission lines to suppress corona discharge and reduce line reactance. Each phase conductor is composed of several sub-conductors with smaller diameters. Each sub-conductor is spaced at a certain distance and arranged in a symmetrical polygonal shape. arranged at the vertices of a regular polygon. Compared with large wires with the same total cross-section, split wires are less likely to produce corona and have higher power transmission capabilities. Split conductors are mainly used on lines with voltages of 220 kV and above. Generally, 220kV has 2 splits, 500kV has 4 splits, Northwest Power Grid has 750kV with 6 splits, and 1000kV has 8 splits.
输电线路带电运行时，通常输电导线表面存在电晕放电现象。这时，电晕放电产生的大量带电粒子聚集在输电导线周围。而针对设置有通信设备的共享铁塔，输电导线又暴露在通信天线发射的电磁波中。由于电磁波具有波粒二象性，通信电磁场与输电导线附近的带电粒子相互作用，从而改变了输电导线的表面电场强度。在导线表面电场强度超出一定范围后，将造成输电线路电磁环境恶化，严重时可能会发生气隙击穿进而影响电网安全运行。When the transmission line is running with electricity, corona discharge usually exists on the surface of the transmission conductor. At this time, a large number of charged particles generated by corona discharge gather around the transmission wire. For shared towers equipped with communication equipment, power transmission wires are exposed to electromagnetic waves emitted by communication antennas. Since electromagnetic waves have wave-particle duality, the communication electromagnetic field interacts with the charged particles near the transmission conductors, thereby changing the surface electric field intensity of the transmission conductors. When the electric field intensity on the surface of the wire exceeds a certain range, the electromagnetic environment of the transmission line will deteriorate. In severe cases, air gap breakdown may occur, thus affecting the safe operation of the power grid.
目前输电导线的表面电场强度不能直接测量，因此无法确定通信电磁场对导线表面电场强度的影响，通常要求通信天线与输电导线保持较远的距离以确保电网的安全运行。At present, the surface electric field intensity of transmission wires cannot be directly measured, so the impact of the communication electromagnetic field on the surface electric field intensity of the wires cannot be determined. Communication antennas are usually required to maintain a long distance from transmission wires to ensure the safe operation of the power grid.
针对缺乏通信电磁场对导线表面电场强度影响的确定方法，结合输电导线表面场强的物理效应，克服当前输电导线表面电场强度无法测试和缺乏计算方法的困难，本发明提供一种共享铁塔设置的通信设备对输电导线场强影响的确定方法。In view of the lack of a method for determining the impact of the communication electromagnetic field on the electric field intensity on the surface of the conductor, combined with the physical effect of the surface field strength of the transmission conductor, and overcoming the current difficulties of being unable to test the electric field strength on the surface of the transmission conductor and lacking a calculation method, the present invention provides a communication system with shared tower settings.

与现有技术相比，本发明实施例的方法采用测试输电线路无线电干扰的方法间接获得通信设备导致的输电导线表面场强的变化量。该方法易于实施，可以定量地确定共享铁塔设置的通信设备发射的电磁场对输电导线场强的影响程度。该方法简单、准确度高，确定的输电导线表面场强的变化量后续可以进一步用于确定共享铁塔设置的通信设备与输电导线之间的的最优防护距离。Compared with the existing technology, the method of the embodiment of the present invention uses the method of testing radio interference of the transmission line to indirectly obtain the change in the surface field strength of the transmission conductor caused by the communication equipment. This method is easy to implement and can quantitatively determine the impact of electromagnetic fields emitted by communication equipment sharing tower settings on the field strength of transmission conductors. This method is simple and highly accurate. The determined changes in field strength on the surface of transmission conductors can be further used to determine the optimal protection distance between communication equipment and transmission conductors in shared tower settings.
利用本发明实施例的共享铁塔通信设备对输电导线场强影响的确定方法，对输电导线型号为4×LGJ-400，500kV单回路水平排列的某共享铁塔确定通信设备导致的输电导线场强变化量，包括：Using the method for determining the impact of shared tower communication equipment on the field strength of transmission conductors according to the embodiment of the present invention, the field strength changes of the transmission conductor caused by the communication equipment are determined for a shared tower with a transmission conductor model of 4×LGJ-400 and a 500kV single-circuit horizontal arrangement. Amount, including:
在确定共享铁塔设置的通信设备导致的输电导线场强变化量时，选择以上参数的实际输电线路作为被试验对象，并选取档距中央、地势平坦的地点作为试验场地。When determining the change in field strength of transmission conductors caused by communication equipment installed on shared towers, select the actual transmission line with the above parameters as the test object, and select a location with flat terrain in the middle of the span as the test site.
在试验场地内，选择输电线路任一侧的边导线地面投影外20m处作为检测点，架设环形天线，并用无线电干扰接收机测量该测量点处的无线电干扰值，具体地，RI0＝42(单位为dB(μV/m))。In the test site, select 20m outside the ground projection of the side conductor on either side of the transmission line as the detection point, set up a loop antenna, and use a radio interference receiver to measure the radio interference value at the measurement point. Specifically, RI0 = 42 ( The unit is dB(μV/m)).
该共享铁塔上所架设的通信天线的波束宽度为60度，增益为15dBi，下倾角为-15度，发射功率为20W。选择能够覆盖以上各参数的通信天线发射电磁波。The communication antenna erected on the shared tower has a beam width of 60 degrees, a gain of 15dBi, a downtilt angle of -15 degrees, and a transmit power of 20W. Choose a communication antenna that can cover the above parameters to emit electromagnetic waves.
发射电磁波时，矢量信号源根据通信调制方式设定相同的调制方式，也即QAM64，并生成源信号送入功率放大器。功率放大器的功率设定为通信天线的发射功率20W。功率放大器将源信号放大后输入到通信天线。按照在共享铁塔上架设天线的方式，调节通信天线的水平方向(也即通信天线与导线在水平面的夹角)和下倾角，使通信天线发出的电磁波主波瓣对准输电导线。When emitting electromagnetic waves, the vector signal source sets the same modulation method according to the communication modulation method, that is, QAM64, and generates a source signal and sends it to the power amplifier. The power of the power amplifier is set to the transmission power of the communication antenna 20W. The power amplifier amplifies the source signal and then inputs it to the communication antenna. According to the method of erecting antennas on shared iron towers, adjust the horizontal direction of the communication antenna (that is, the angle between the communication antenna and the conductor on the horizontal plane) and downtilt angle so that the main lobe of the electromagnetic wave emitted by the communication antenna is aligned with the transmission conductor.
这时，在通信天线生成的电磁波环境里，测量检测点的无线电干扰为RI1＝42。At this time, in the electromagnetic wave environment generated by the communication antenna, the radio interference at the measurement detection point is RI1 =42.
在输电导线型号为4×LGJ-400时，分裂数、半径均为已知数(如图4所示)，确定其无线电干扰与表面场强具有如下关系：RI0＝a+3.5E0。When the transmission conductor model is 4×LGJ-400, the splitting number and radius are both known numbers (as shown in Figure 4). It is determined that the radio interference and surface field strength have the following relationship: RI0 =a+3.5E0 .
采用镜像法计算输电导线表面场强，并由皮克公式求得E0＝16.20kV/cm。The mirror method is used to calculate the surface field strength of the transmission conductor, and E0 =16.20kV/cm is obtained based on Pic's formula.
施加来自通信设备电磁波后，输电导线的无线电干扰为：After applying electromagnetic waves from communication equipment, the radio interference from power transmission conductors is:
RI1＝a+3.5E1(n)。RI1 =a+3.5E1 (n).
由式(1)和(2)可求得施加电磁场后的导线输电表面场强E1：From formulas (1) and (2), the field strength E1 of the conductor transmission surface after the electromagnetic field is applied can be obtained:
E1＝(RI1-RI0)/3.5+E0。E1 =(RI1 -RI0 )/3.5+E0 .
针对该输电导线型号为4×LGJ-400、500kV单回路水平排列的输电杆塔，在检测点上，接收到的无线电干扰没有变化，可以间接得出在通信天线加入前后，输电导线的表面场强没有变化。这是因为通信设备发射的电磁波功率较小，与输电导线之间的距离较远，尚不足以改变导线表面场强。For the transmission conductor type 4×LGJ-400, 500kV single-circuit horizontally arranged transmission pole tower, at the detection point, the received radio interference does not change, it can be indirectly concluded that the surface field strength of the transmission conductor before and after the communication antenna is added no change. This is because the electromagnetic wave power emitted by communication equipment is small and the distance from the transmission wire is long, which is not enough to change the field strength on the surface of the wire.
