Introduction to 0
In the process of continuous development in the new century, the power system occupies a major position in China's social and economic development, and at the same time, it also adds some pressure to China's power development. Power marketing can well alleviate the problems faced by power system, so it is imperative to carry out power marketing.
1 summary of automatic remote meter reading technology
Automatic meter reading technology refers to: in the process of growing power system, automatic meter reading technology came into being because of the heavy work of meter reading. In the current power marketing, the more popular meter reading technologies are: wired transmission, wireless transmission, low-voltage wired carrier technology, data network transmission and so on. At present, the most widely used technology in China is low-voltage wire carrier technology. Automatic remote meter reading technology refers to the front-end acquisition system, communication system and data processing system. The front-end acquisition system is mainly responsible for collecting time-related information. In the specific implementation process, the collection work can be divided into remote meter reading and on-site meter reading. Communication system refers to meter reading. Data-related transmission carriers can generally be divided into wired communication and wireless transmission. Data processing refers to analyzing the collected data through some software to meet the relevant information needed for the development of power system.
2 Application of Remote Meter Reading Technology in Power Marketing
(1) can realize real-time data transmission. In the process of remote meter reading, the information is collected by using relevant acquisition methods, and then the data is distributed, including the data of each meter, meter reading time, meter reading interval, etc. , set in low-voltage carrier equipment, and the acquisition begins at the time of acquisition. Then, upload the data to the server. The application of remote meter reading technology can effectively improve work efficiency and ensure the accuracy of meter reading data. On the other hand, because its acquisition time is designed in advance, the power system can make appropriate adjustments to the irrationality existing in the power system according to the analysis of relevant data.
(2) Effective data storage and real-time data query can be realized. In the process of remote meter reading, the maximum utilization rate of computer server can be realized. This can not only solve the problem of remote meter reading, but also test the power consumption of users in time. At the same time, according to the actual demand of power supply marketing, the user's load curve can be drawn directly in the form of charts, and the user's electricity consumption data can be accurately described for convenient inquiry.
(3) The application of remote meter reading technology is actually a computer with remote function, which can detect data and transmit data to the server at the same time. It is precisely because of this that we can achieve the goal of optimizing power marketing and provide certain technical support. In the actual operation process, it is often possible to give an alarm to abnormal lines and predict some related problems. Remote meter reading can ensure the stability of data and deal with some unreasonable consumption.
(4) Relevant parameters can be set scientifically to increase the flexibility of meter reading, and at the same time, remote meter reading technology can be controlled, mainly in the management of each user through the application of MIS system. The practical significance is that it can effectively urge users to pay the electricity bill, cut off the power supply, and restore the electricity consumption, which greatly improves the working efficiency of the power system. Relieve the pressure of excessive power grid load.
3. Problems and improvement measures in the application of automatic meter reading technology.
(1) Problems to be optimized in the application of remote meter reading technology: As far as the application process of remote meter reading technology is concerned, it occupies a very high position. However, there are still some solutions to be optimized during its operation, such as:
1) There are some errors in the data of meter reading in a specific environment, which are caused by the uneven installation position of the meter and the lack of clear planning; At the same time, there are no relevant meter reading rules. In addition, when communication is transmitted, the signal source intensity is not high;
2) In some high-end residential areas, some meter reading terminals have certain errors, so they cannot be received in time;
3) The information concentrator can only be installed on the low voltage side, not on the high voltage side. This problem has not been solved at present.
(2) Countermeasures for problems in remote meter reading.
1) In view of the errors in the process of meter reading, some relevant requirements can be made for meter reading to ensure the order of meter reading. At the same time, before installing the meter, the installation position of the meter should be designed to avoid the phenomenon of random installation of the meter.
2) When designing some high-grade residential areas, we should strengthen the design planning of internal lines in the residential areas to ensure that the terminals can effectively receive relevant data and information;
3) Strengthen the investment in power grid technology research, ensure the development of the whole power grid technology, optimize the use of related technologies, improve the utilization rate and increase the benefit of power grid engineering.
4 the significance of remote meter reading technology in power grid
With the rapid development of electric power technology, the application of remote meter reading technology has entered a new stage in the development level of electric power in China. Its application effectively improves the working efficiency of power system, and at the same time, it also promotes the higher improvement of communication quality, with a qualitative leap in speed than before, and the data that can be transmitted greatly meets the demand of power market. So we can use some related communication tools to repair some hardware. This can improve the reliability of the system while reducing the cost, and can also greatly reduce the cost of power transmission from the terminal to the main station; At the same time, the operation of automatic control system of distribution network and the connection of remote meter reading system can ensure the improvement of transmission efficiency and the unification of the two systems, and the reference data of various projects can be merged. Through the continuous input of advanced technology into power grid engineering, it can promote the sustainable development of remote meter reading technology and expand the benefits of this technology. The application of remote meter reading system technology makes the information of the whole power system fully managed and realizes all-weather control of the power grid. After the normal operation of the system, the income effect of the power supply company has been effectively improved, the electricity consumption of each household has been fundamentally controlled, and the bad debts of the power supply company have been greatly changed.
5 abstract
With the continuous reform of state grid engineering, automatic remote meter reading technology has been widely used. To a certain extent, it improves the benefit of power supply company and relieves the work pressure; But also can effectively improve the power utilization rate. Because there are some errors in remote meter reading at present, we still need several major scientific and technological inputs to continuously improve the utilization rate of electric energy.
