This invention relates to the field of industrial automation and control network technology, and discloses a real-time synchronization method system for LonWorks networks based on digital twin variables. Applied to LonWorks fieldbus networks, it is implemented based on a heterogeneous node system consisting of a general-purpose processing module, a LonTalk protocol processing module, and a high-speed serial communication bus. The general-purpose processing module carries a manager, the LonTalk protocol processing module maintains standard LonWorks network variables and has a built-in LonTalk protocol stack, and the high-speed serial communication bus transmits DTVP data frames. This invention achieves a significant leap in node computing power, freeing nodes from the limitations of dedicated communication chips and allowing them to directly utilize the high performance of industry-leading general-purpose microcontrollers to easily handle complex control algorithms, real-time data filtering, lightweight artificial intelligence inference, and other complex tasks.

The application provides a new energy flexible direct transmission system flexible direct current station adaptive control method, including obtaining a first reference value according to an equivalent sequence network variable, electrical quantity data and a pre-fault reference value, the first reference value representing a lower limit value of an internal electromotive force reference value of a virtual synchronous machine meeting a current limiting requirement; obtaining a second reference value according to the equivalent sequence network variable and a maximum fault current, the second reference value representing a lower limit value of an internal electromotive force reference value of a virtual synchronous machine meeting a current differential protection action criterion; obtaining a post-fault reference value according to the first reference value, the second reference value and a low voltage ride through voltage threshold value, so as to perform adaptive control of the flexible direct current station. The method does not significantly increase the complexity of the system, can adaptively adjust the post-fault reference value according to the fault severity, takes into account the current limiting requirement and the correct action demand of the current differential protection, at the same time prevents the occurrence of repeated low voltage ride through phenomenon, and effectively improves the reliability of the differential protection under the power electronic weak feedback characteristic.

Technology described herein can employ dynamically changing network variables and / or context, in realtime, to determine one or more possible contexts that can lead to network function (NF) misconfiguration, NF mismatch and / or key performance indicator (KPI) degradation. In an embodiment, an example system can comprise a processor, and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising determining a working configuration of a network function, and detecting a misconfiguration between a specified configuration and the working configuration of the network function, wherein the detecting is based on a context known to be associated with the misconfiguration. Analysis of context can comprise analyzing, based on an artificial intelligence model, the contexts of the network function as compared to known and / or stored contexts.
