What are the working principles of energy storage substations
The substation is a new type of grid system that incorporates modern information systems into the traditional energy network. The traditional power system has low energy utilization, low interactivity and strong interactivity. So that the grid has better controllability and greater possibilities. So, let us take a look at the working principles of energy storage substations.
Energy storage substation is the development direction of the future power grid. In these links, smart substation is undoubtedly the core part. It has penetrated into all aspects of power generation, transmission, transformation, and communication.
Energy storage substation is a layered construction of smart primary equipment and networked secondary equipment. Smart primary equipment mainly includes smart transformers, smart high-voltage switchgear, electronic transformers, etc. For example, smart transformers and control systems are connected through communication optical fibers to realize the inside of the substation. A modern substation for information sharing and intercommunication between intelligent electrical equipment. The status parameters and operating data of the transformer can be grasped instantly.
On the basis of the communication of the primary equipment, the hierarchical construction of networked secondary equipment requires a wide range of applicability and a powerful communication protocol. Through a series of standardization of equipment, only various equipment can interoperate through the protocol to make it form A standardized output can realize the seamless connection of the system and realize the intelligentization of the substation. This communication protocol realizes the standardization of smart substation project operation for the standard, and makes the project implementation of smart substation standardized, unified and transparent.
The safety and reliability of energy storage substations are the insurmountable principles of the power grid system. There are many equipment from different manufacturers connected, and the reliability of the intercommunication between equipment has also become a topic. In order to ensure the reliable operation and response speed of the entire smart substation system, as smart substation equipment is divided into three layers: process layer, bay layer, and station control layer, it depends on various tests and system joint adjustments during substation detection.
In general, the testing items of smart substations mainly include process level equipment testing, station control level equipment testing, and main system function testing. Therefore, the testing of smart substations needs to be based on the particularity of smart substations, and corresponding testing should be formulated during testing. plan.
