1. Overview
With the country's economic development, the demand for electric energy is growing rapidly. The traditional power transmission method is the centralized power generation of large-scale power systems. High cost, poor interaction, and difficult security and stability analysis. Especially with the strengthening of people's awareness of environmental protection, thermal power generation as the main power generation method is gradually abandoned, and the ultra-large-scale power system is beginning to find it difficult to adapt to the increasingly diverse power supply needs of users. and reliability requirements. With the development of the serial to wifi converter Internet of Things industry and the promotion of smart grids in the strategic decision-making of national economic development, and with the continuous expansion of the application of the Internet of Things, applying it to the power system can not only improve the security and failure resistance of the entire system but also realize Information exchange with users will ultimately achieve the goal of energy saving, emission reduction, safety, reliability and compatible interaction of the smart grid.
2. Application Chengdu Ebyte Electronic Technology Co., Ltd. is committed to independent research and development and customer customization needs. It also conducts in-depth exploration and research in the field of NB-IOT, and has achieved very good research results. It can provide comprehensive IOT analysis solutions. The NB-IOT module data transmission station has the characteristics of ultra-low power consumption, super penetrating power, wide coverage, and large access capacity. At the same time, the three major domestic operators have laid more and more NB-IOT base stations, improving the The NB-IOT high-quality network in the whole area, the actual test can cover the urban pipeline with a depth of about 3m underground. For a circuit system, there are many and scattered collection points, a large amount of transmitted data, and high real-time requirements, so NB-IOT technology is perfect. Based on the NB-IOT module and the micro smart grid sensor, it can monitor the ground current leakage of underground or above ground cables, the concentration of harmful gases, water level monitoring, the temperature and humidity of underground cable tunnels, partial discharge, the condition of the manhole cover where the cable is located, location information, voltage box status etc.
1. 7x24 hours remote monitoring of temperature, harmonics, current, voltage, three-phase imbalance and other parameters at any point of the power grid, so that the operating status of the entire power grid can be seen at a glance
2. When a fault occurs, modbus tcp gateway it can accurately and timely locate the fault location, shorten the repair time, and avoid personal and property losses.
3. Compare and analyze the data in real time, and keep abreast of the aging of the line due to heavy load and overcurrent.
4. The ultra-low power consumption NB-IOT technology ensures the long-term stable work of the test point.
5. Replace the traditional electrical safety monitoring system to reduce equipment installation costs. With the continuous advancement of science and technology, all kinds of data will be aggregated to the grid data center faster and more accurately. It is becoming more and more urgent to build a new generation of smart grid. serial port ethernet converter The current smart grid is not yet mature, such as electric load forecasting, line Loss calculation, power asset system, background data analysis and many other functions need to be integrated. Smart grid is still a long way from multi-objective and big data.
