Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic environment of power system, and more specifically, to a system and method for acquiring long-term observation data of corona effect of high-altitude AC transmission line. Background Art

[0002] At present, environmental protection usually only conducts corona effect tests on AC transmission lines in good weather without rain or snow. The amount of data obtained through short-term measurements is very small, and it is difficult to fully reflect the characteristics and level of the corona effect. At the same time, AC corona discharge is more obvious in bad weather such as rain, snow, fog, etc., and the electromagnetic environment impact such as audible noise and radio interference generated is greater, which leads to more complaints from people. Therefore, it is urgent to carry out long-term observations to obtain the audible noise and radio interference levels in various weather conditions. In addition, the corona effect control value is also formulated according to the long-term operation level, such as the audible noise rainy day L 50 Value, radio interference good weather average.

[0003] my country's energy and load are inversely distributed. At present, clean energy from high-altitude areas in the west is continuously transmitted to the east through high-voltage power grids, and ultra-high voltage AC and DC power grids in high-altitude areas have developed rapidly. Due to the lack of in-depth research on the corona effect of high-altitude transmission lines in the world and the lack of basic data, it is urgent to obtain the characteristics and level of the corona effect of actual high-altitude transmission lines to guide and optimize the subsequent engineering design and construction. my country's high-altitude AC transmission lines are mainly located in the Qinghai-Tibet Plateau and other places, with high altitudes and harsh climatic conditions. At the same time, the lines are mainly located in mountains and their surrounding areas, with sparse population and difficulty in obtaining electricity at observation points. The cost of directly erecting municipal power lines is high, and the construction period is long, which is difficult to meet the needs of rapid engineering testing and research. In addition, some areas are located in scenic spots or nature reserves, and power lines cannot be erected. Traditional long-term observation stations have many devices, even equipped with summer and winter auxiliary equipment such as air conditioners and heaters, with high power consumption. Conventional wind-solar complementary modules are difficult to meet power supply needs. Larger-scale wind-solar complementary power supply not only requires a large amount of land, which is easy to damage the fragile ecological environment of the plateau, but also improper layout will affect the normal measurement of noise and radio interference. Therefore, it is necessary to reduce equipment power consumption and optimize the power supply system and measurement cycle. At the same time, traditional long-term observations with a year as the cycle not only have a long test time, but are also difficult and dangerous to implement in some high-altitude areas.

[0004] Therefore, a system and method for obtaining long-term observation data of the corona effect of high-altitude AC transmission lines is needed. Summary of the invention

At the same time, through the short-term observation of 3 months in autumn, the statistical results closest to the annual long-term observation are obtained, which are highly accurate and timely; using the large-capacity battery of the electric vehicle as a backup power supply, in extreme cases, it can quickly go to the power supply point for charging and replenishing energy, further improving the reliability of power supply. The present invention can be used for the acquisition of corona effect characteristics and levels of AC transmission and transformation projects, environmental protection, and optimization design of high-altitude transmission lines. The system 100 for obtaining long-term observation data of corona effect of high-altitude AC transmission lines provided by the embodiment of the present invention includes: a power supply module 101, a meteorological parameter measurement module 102, and a corona effect measurement module 103.

[0044] Preferably, the power supply module 101 is connected to the corona effect measurement module, and is used to supply power to the corona effect measurement module.

[0045] Preferably, the power supply module comprises: a wind-solar power generation complementary module and an electric vehicle power supply module;

[0046] Among them, the wind-solar power generation complementary module and the electric vehicle power supply module can switch power supply; the wind-solar power generation complementary module is equipped with a first battery pack, and the electric vehicle power supply module includes: an electric vehicle body and a second battery pack, and the wind-solar power generation complementary module can charge the corona effect measurement module, the first battery pack and the electric vehicle body; the wind-solar power generation complementary module and the electric vehicle power supply module both have power display and alarm functions.

[0047] Combination Figure 2 As shown, in the present invention, the system for obtaining long-term observation data of the corona effect of high-altitude AC transmission lines includes: an electric vehicle power supply module, a wind-solar complementary power generation module, a corona effect measurement module and a meteorological parameter measurement module. Among them, the wind-solar complementary power generation module is composed of a wind turbine, a solar panel, a converter and a battery pack, the low-power corona effect measurement module is composed of a computer, an audible noise measurement device, and a radio interference measurement device, and the meteorological parameter measurement module is composed of a meteorological station and a weather phenomenon meter. Under normal circumstances, the wind-solar complementary power generation module supplies power to the low-power corona effect measurement module and charges the electric vehicle. When the wind-solar complementary power generation module is insufficient, the electric field vehicle supplies power to the low-power corona effect measurement module.

[0048] In the present invention, the electric vehicle power supply module should be equipped with a large-capacity lithium battery pack, with strong off-road performance and large space, which can adapt to the use needs of complex plateau terrain, and can also power the corona effect measurement module when necessary. The wind-solar complementary power generation module is equipped with a battery pack, which can generate sufficient power of not less than 600 watts when there is light and wind during the day. On the one hand, it is used to power the measurement module, and on the other hand, it can charge the battery pack and the electric vehicle power supply module. Both the wind-solar complementary power generation module and the electric vehicle power supply module are equipped with battery packs, and have power display and alarm functions, which are convenient for timely switching of power supply modes.

[0049] The entire measurement system of the present invention can operate stably for a long time without relying on the mains power supply. In the extreme case of long-term lack of good light and wind power charging, the measurement system can operate continuously for more than 15 days, and at the same time, the electric vehicle can find a charging station for rapid energy replenishment, thereby further improving the reliability of power supply. The measurement module can quickly switch between the wind-solar hybrid power generation module and the electric vehicle power supply, and neither of these two power supply methods will interfere with the normal operation of the measurement system.

[0050] Preferably, the meteorological parameter measurement module 102 is connected to the corona effect measurement module for measuring meteorological data.

[0051] Preferably, the meteorological parameter measurement module comprises: a meteorological station, a weather phenomenon instrument and a solar power supply panel; wherein,

[0052] The meteorological station is used to obtain meteorological parameter data; wherein the meteorological parameter data includes: temperature, humidity, rainfall, snowfall, air pressure and / or wind speed;

[0053] The weather phenomenon instrument is used to identify the weather type;

[0054] The solar power supply panel is used to supply power to the weather station and the weather phenomenon instrument.

[0055] In the present invention, the meteorological parameter measurement module is composed of a weather station and a weather phenomenon instrument, and uses low-power equipment and is equipped with a solar power supply panel to further reduce the power demand of the equipment. The meteorological parameter measurement module can identify various weather types and obtain various meteorological parameters such as temperature, humidity, rainfall, snowfall, air pressure, wind speed, etc.

[0056] Preferably, the corona effect measurement module 103 is used to measure the corona effect data at the target measuring point position of the high-altitude AC transmission line in autumn, and determine the long-term observation data of the corona effect based on the meteorological data and the corona effect data.

[0057] Preferably, the corona effect measurement module comprises: an audible noise measurement device, a radio interference level measurement device and a computer; wherein,

[0058] The audible noise measuring device is connected to the computer and is used to measure the audible noise at a target measuring point of a high-altitude AC power transmission line in autumn to obtain audible noise measurement data;

[0059] The radio interference level measuring device is connected to the computer and is used to measure the radio interference at the target measuring point of the high-altitude AC power transmission line in autumn to obtain radio interference level measurement data;

[0060] The computer is used to determine short-term statistical data of corona effect on high-altitude AC transmission lines in autumn based on the meteorological data, audible noise measurement data and radio interference level measurement data, and use the short-term statistical data of corona effect on high-altitude AC transmission lines in autumn as long-term observation data of corona effect on high-altitude AC transmission lines.

[0061] Preferably, the short-term statistical data of corona effect of AC transmission lines at high altitude in autumn include: L 50 values ​​and average values ​​of radio interference levels in heavy rain and good weather.

[0062] Combination Figure 2 As shown, in the present invention, the corona effect measurement module is a low-power corona effect measurement module, which reduces the overall power consumption of the system by selecting low-power measurement equipment, and utilizes autonomous power supply and short-term observations in autumn to quickly obtain the statistical values ​​of the corona effect of high-altitude AC transmission lines.

[0063] In the present invention, the low-power corona effect measurement module is composed of a low-power computer (such as a MIN IPC), a low-power audible noise measurement device and a low-power radio interference level measurement device. The total power consumption is reduced by selecting low-power devices, and the overall power does not exceed 300 watts.

[0064] In the present invention, autumn observation is carried out in high altitude areas from September to November each year. In this season, the temperature and rainfall are relatively suitable, and the statistical values ​​of quarterly short-term observations are closest to those of annual long-term observations. Statistical analysis is performed on meteorological data, audible noise measurement data, and radio interference level measurement data obtained from autumn observations to determine short-term statistical data on the corona effect of high altitude AC transmission lines in autumn. Among them, the statistical data on the corona effect of high altitude AC transmission lines include but are not limited to: L in rainy and good weather 50 Values, average values ​​of radio interference levels in heavy rain and good weather.

[0065] Since the statistical values ​​of the three-month observation in autumn are basically equivalent to the annual observation statistical values ​​over one year, they can represent the actual level and characteristics of the line corona effect. Therefore, the short-term statistical data of the corona effect of high-altitude AC transmission lines in autumn obtained through statistical analysis can be used as the long-term observation data of the corona effect of high-altitude AC transmission lines obtained through long-term observation.

[0066] The system based on the present invention reduces the overall power consumption of the system by selecting low-power measurement equipment, and utilizes autonomous power supply and short-term observation in autumn to quickly obtain long-term observation data of the corona effect of high-altitude AC transmission lines.

[0067] The following specifically illustrates the embodiments of the present invention.

[0068] The embodiments of the present invention are based on Figure 2 The acquisition system of the long-term observation data of the corona effect of the high-altitude AC line shown in the figure is realized. The acquisition process mainly includes:

[0069] Step 1: Pre-select the location of the long-term observation point of the high-altitude AC transmission line, and transport the wind-solar hybrid power generation module, corona effect measurement module, and meteorological parameter measurement module to the observation point by electric vehicle before September to November in autumn.

[0070] Step 2: Install and fix the wind-solar complementary power generation module, corona effect measurement module, and meteorological parameter measurement module. The wind-solar complementary power generation module, meteorological parameter measurement module, and electric vehicle should be kept at a certain distance from the corona effect measurement module. Certain noise reduction measures can be taken to avoid additional noise on rainy days that affects corona effect observation.

[0071] Step 3: Debug the wind-solar complementary power generation module, corona effect measurement module, and meteorological parameter measurement module, and connect the wind-solar complementary power generation module, corona effect measurement module, and electric vehicle. Under normal circumstances, the wind-solar complementary power generation module can supply power to the corona effect measurement module and the electric vehicle. Under extreme circumstances, the electric vehicle supplies power to the corona effect measurement module.

[0072] Step 4: Turn on the measurement system before September 1 to simultaneously measure audible noise, radio interference and meteorological parameters.

[0073] Step 5: Continue observing until November 30.

[0074] Step 6: Collect statistics on audible noise and radio interference from September 1 to November 30 in the entire autumn, and obtain the L of audible noise in rainy days and good weather. 50 Values, average values ​​of radio interference levels under heavy rain and good weather, as long-term observation data of corona effect on high-altitude AC transmission lines.

[0075] It should be noted here that the entire measurement system adopts a relatively compact layout to reduce land occupation and vegetation damage. The reason why the three months of autumn were selected as the observation period is based on the statistical results of two years of long-term observation of three high-altitude AC transmission lines on the Qinghai-Tibet Plateau. Under normal circumstances, the average values ​​of audible noise rainy days, radio interference heavy rain and good weather in autumn are less than 1dB different from the statistical values ​​of one-year long-term observation. Although the observation time is only one-fourth of a year, which is greatly reduced, the statistical values ​​are almost the same as those of one-year long-term observation, which can represent the level and characteristics of the corona effect of transmission lines.
