With the power grid companies to speed up the construction of a strong smart grid, intelligent transformer technology level will enhance the smart grid construction has a huge role in promoting. While the transformer on-line monitoring function and real-time feedback interactive function will be inserted for the traditional transformer wings of intelligent development.
Global transformer monitoring system for rapid development
Technavio released the global transformer monitoring system market research report, 2016 - 2020, the global transformer monitoring system market compound annual growth rate of up to 36%. For the Asia-Pacific region, the rapid economic development and rapid population growth is bound to promote the market demand for transformer growth to strengthen the distribution. These large-scale transformer networks require continuous monitoring to prevent failures during transmission and distribution, resulting in power outages. Therefore, the next five years, the Asia-Pacific region has great potential for transformer monitoring market.
Not only that, industrial, commercial and residential users demand for electricity is also growing, so as to stimulate the power companies to speed up the expansion of power grids, and the installation of distribution transformers become a top priority, because it can not only expand the scope of distribution, but also The upgrading of the aging of the transformer to further promote the market demand for monitoring growth.
It can be seen that in the coming years, stable and affordable electricity supply is the key to economic growth, both in developed and developing countries. Transformers, as key high-cost equipment in transmission and distribution systems, will play an important role, so their operations will require continuous real-time monitoring to ensure stable and reliable power delivery.
Advantages of Transformer On - line Monitoring
With the development of modern sensing technology, microelectronics technology and computer technology, the state monitoring of high voltage equipment such as transformers has a solid foundation. Compared with the traditional transformers, intelligent transformers with intelligent online monitoring capabilities, increasingly become an important power grid construction equipment.
Transformer on-line monitoring is based on microprocessing technology, which integrates sensor, data collection, communication system and data analysis function in one, through continuous monitoring in a period of time state parameters, timely capture transformer early warning information, according to the transformer parameters Change the trend to determine the transformer operating status. Compared with the traditional transformer, intelligent online monitoring function has the following advantages:
Effectively prevent the occurrence and development of various failures of the transformer, and reduce the economic losses caused by an unexpected power outage. Real-time monitoring of the transformer in operation, to make up for the lack of conventional test and detection means. Although there are some limitations in the internal fault prediction based on the dynamic information of the captured transformer, it is still the most effective technical basis for the development of the transformer maintenance plan. It is of great significance.
With a high degree of reliability, maintenance-free and self-test function. Once the monitor itself has a problem, can automatically send sound and light call alarm signal. Therefore, it eliminates the problem of misjudgment caused by the abnormality of the detection device in the conventional detection method.
Significant economic benefits. Transformer online monitoring system of investment costs, including sensors and intelligent monitoring software in two parts. According to statistics at home and abroad, a complete set of transformer online monitoring system costs about 1% of the transformer price. However, due to the timely detection of the transformer early failure, so that the operation and maintenance costs reduced by 75%, the annual cost savings equivalent to 2% of the transformer price, and can extend the service life of 10 years or so, its economic benefits considerable.
Development Trend of Transformer On - line Monitoring
On the current application of online monitoring technology transformer, although there are still anti-electromagnetic interference is not strong, short life, high prices and other defects, but because of its conventional means of detection is unparalleled superiority, all the problems are Will be gradually resolved in the development.
From the policy level, due to the demand for smart grid construction to promote, as well as scientific research institutes, online monitoring company research and development efforts continue to increase, online monitoring technology application work is steadily advancing, not only to promote the transformer maintenance procedures, management methods to follow And will inevitably lead to the establishment of a standardized state maintenance management system, as well as the final unity of technical standards.
From the economic level, with the domestic online monitoring equipment production and software development companies to strengthen research and development efforts and similar foreign competition, as well as the strong demand for power grid and other factors, not only the price of its hardware and software products will be significantly reduced, and cost Will also be greatly improved.
From a technical level, the hardware device will be more intelligent direction, maintenance-free will be higher. The use of intelligent sensors, so that the electromagnetic interference can be effectively suppressed; with the widespread use of new materials, chromatography analysis of breathable film and other equipment life will be extended. Fault analysis software system will also be offline test, equipment status, operating data and other information organic integration, to carry out integrated online diagnosis, different systems of online monitoring data will be shared through the network.
With the power grid companies to speed up the construction of a strong smart grid, intelligent transformer technology level will enhance the smart grid construction has a huge role in promoting. While the transformer on-line monitoring function and real-time feedback interactive function will be inserted for the traditional transformer wings of intelligent development.
