Self-adaptive load control method and system based on transformer working condition real-time monitoring

Abstract

The invention discloses a self-adaptive load control method and system based on transformer working condition real-time monitoring. According to the method and system, a user with a lower importance level is cut off when a load needs to be cut off according to the load condition of a transformer monitored in real time, the power supply of a user with a higher importance level is guaranteed; when the load of the transformer is reduced to a certain degree, and the power supply of the user can be recovered according to the importance level of the user, so that the user with the high importance level can be uninterruptible, and the user with the low importance level can be shortest in power failure time. The method and system do not need to depend on pre-estimated load to limit the power of the users in advance. In the prior art, a load increase condition cannot be accurately predicted in an existing load control method for limiting the power of users in advance by adopting pre-estimated load, as a result, the power failure time is too long, the user experience is reduced, and the power supply cannot be recovered timely when the power consumption peak passes. With the method and system adopted, the above problems can be solved.

Description

technical field [0001] The invention relates to the technical field of distribution by transformer capacity method, in particular to an adaptive load control method and system based on real-time monitoring of transformer working conditions. Background technique [0002] With the rapid development of social economy and electric power science and technology, people's demand for electricity is also increasing. However, the capacity of distribution transformers is difficult to keep up with the growth of users' electricity load, which may easily cause overload operation of transformers. The overload operation of the transformer will have a serious impact on the equipment itself. When the transformer is overloaded by 1.3 times, the allowable continuous operation time is 1 to 2 hours. When the overload is 1.6 times, the allowable continuous operation time is 15min to 30min. When doubled, the allowable continuous working time is 8 to 15 minutes. And the upper oil temperature of th...

Problems solved by technology

[0004] The present invention provides an adaptive load control method and system based on real-time monitoring of transformer operating conditions, which is used to solve the problem that the existing load control method that uses estimated load to limit power for users in advance is prone to failure to accurately predict the load growth situation. Prolonged power outages, degraded user experience, and technical issues that fail to restore power in time when peak usage has passed
