Description
Technical Field

Background
At present, the scale of a modern power grid is gradually enlarged, the structure is gradually complicated, and a traditional relay protection mode has certain defects. If the traditional backup protection is difficult to set and match, and is influenced by a power grid framework and an operation mode, the backup protection is easy to mismatch, unexpected cascading tripping operation may occur in a heavy-load power flow transfer process and the like, and especially the relay protection performance is required to be higher at the development front edge of an intelligent clean power grid with new energy access, alternating current-direct current hybrid connection and the like. With the development of smart grid information sharing technology and optical fiber communication technology, in recent years, hierarchical protection by using data information and even wide area measurement information in a transformer substation range is one of research directions for overcoming the defects of traditional relay protection.
Generally, hierarchical protection divides the protection hierarchy into local layer protection (also called spacer layer protection), station domain layer protection, and wide area layer protection. And (4) aiming at the stratum protection surface to a single protection object, and independently deciding, which is the same as the traditional relay protection. The newly-established station domain layer protection and wide area layer protection comprehensively utilize information in the range of the full transformer station and information of a plurality of transformer stations to carry out comprehensive decision, and the non-delay protection functions such as station domain redundancy differential protection and the like and the delay protection functions such as near backup or far backup and the like are executed.

Referring to fig. 1 and fig. 2, an embodiment of the present invention provides a hierarchical protection system 100 based on a virtual container, where the hierarchical protection system 100 includes a stratum protection system, a station domain layer protection system, and a wide area layer protection system, and the hierarchical protection system 100 includes:
a plurality of data exchange processing modules 10, configured to encode and decode SV data and GOOSE packets at all intervals of a substation, so as to perform a non-delay protection function in the substation domain layer protection and the wide area layer protection;
the main control management module 20 generates a plurality of hierarchical protection virtual containers 21 that are isolated from each other, and the plurality of hierarchical protection virtual containers 21 are respectively in communication connection with the plurality of data exchange processing modules 10 and are respectively used for receiving SV data and GOOSE messages at intervals corresponding to a transformer substation, so as to execute the functions of delay protection in the substation domain layer protection and the wide area layer protection.
In the embodiment of the present invention, a system architecture of a hierarchical protection system 100 is shown in fig. 1, where the system 100 includes a plurality of data exchange processing modules 10 and a master management module 20.
The plurality of data exchange processing modules 10 have high operation speed and high real-time processing capability, and constitute a real-time core of the hierarchical protection system 100. Specifically, the plurality of boards are responsible for encoding and decoding SVs (Sampled values) and GOOSE (Generic Object Oriented Substation events) at all intervals of the Substation, performing 1588 time synchronization, data interpolation and message filtering, undertaking real-time tasks such as data sharing and information interaction with the plurality of hierarchical protection virtual containers 21 in the master control management module 20, and performing non-delay protection functions in station domain layer protection and wide area layer protection, such as station domain redundancy differential protection and wide area pilot protection.
The master control management module 20 interacts with the plurality of data exchange processing modules 10, and is configured to receive SV data and GOOSE messages of all intervals of the substation. The master management module 20 is a virtual container carrier of the hierarchical protection system 100, and generates a plurality of hierarchical protection virtual containers 21 isolated from each other, such as wide area layer partition virtual containers, station domain layer transformer protection virtual containers, station domain layer bus protection virtual containers, and the like shown in fig. 2. The plurality of hierarchical protection virtual containers 21 respectively interact with the plurality of data exchange processing modules 10. The SV data and GOOSE messages received by the master control management module 20 for all the intervals of the receiving substation are provided to the corresponding hierarchical protection virtual container 21 or the adjacent substation, and a delay protection function is provided for the substation area layer and the wide area layer which are insensitive to the running time.
According to the technical research report of 'novel hierarchical protection principle and construction mode research applicable to alternating current-direct current hybrid connection, high-proportion new energy access and machine-network cooperation' of the Guangdong power grid, the method comprises the following steps:
the station domain layer has the delay protection functions of: A) differential protection of a transformer with redundant station areas, low-voltage side re-voltage over-current protection, low-voltage side zero-sequence overvoltage protection and low-voltage side overload protection (mainly aiming at a system of 110kV or below); B) the station communication power supply voltage loss near backup protection; C) bus differential protection (mainly aiming at the condition that a system of 110kV and below is not provided with bus differential protection); D) the failure protection of the circuit breaker; E) intra-site information loss protection, etc.
The wide area layer has a time delay protection function and has wide area near backup protection, far backup protection and the like.
Illustratively, a differential protection virtual container of a 110kV station domain redundant transformer can be set, and the protection action time is set. The differential protection virtual container of the 110kV station domain redundant transformer can acquire information on three sides of the transformer from the data exchange processing module 10 in real time, and perform protection calculation, so that a station domain layer has a time delay protection function. In addition, when the on-site layer protection fails, the fault cannot be removed, and the fault time reaches a setting value, the 110kV station domain redundant transformer differential protection can be used for removing related faults, so that the operation safety of the power system is protected.
It should be noted that, instead of sending the SV data and GOOSE packets to the corresponding hierarchical protection virtual container when the protection of the local layer fails, the data exchange processing module 10 may also provide the SV data and GOOSE packets to the corresponding hierarchical protection virtual container 21 during normal operation, so as to implement that the local layer and the wide area layer that are insensitive to the operation time have a delay protection function.
In addition, the operation time is insensitive to the operation time, according to the operation specification of a southern power grid or a national power grid, the action time without delay protection such as differential quick-break and the like is within 30-40ms (related to the voltage grade), and in order to ensure the selectivity of relay protection, the action time of backup protection is longer than the action time of main protection by a difference delta t (according to setting). Therefore, the time insensitive boundary is [ (30-40) + Δ t ] ms. According to the technical research report of 'novel hierarchical protection principle and construction mode research applicable to alternating current-direct current hybrid connection, high-proportion new energy access and machine-network cooperation' of the Guangdong power grid, the action delay of the communication power supply voltage loss near backup protection for the station can be set to 0.3 s.
In the embodiment of the present invention, because the hierarchical protection virtual containers 21 are safe and reliable lightweight operating system-level virtualization, applications can be run in an isolated manner, when a failure occurs in a certain hierarchical protection virtual container 21, because the hierarchical protection virtual containers 21 are isolated from each other, the hierarchical protection virtual container 21 does not affect the normal operation of other hierarchical protection virtual containers 21, and thus, faster modular services can be provided by using fewer management resources.
As can be seen from the above, in the hierarchical protection system 100 based on a virtual container in the embodiment of the present invention, the virtual container is applied to a substation hierarchical protection system, a conventional real-time core is combined with the virtual container, a plurality of data exchange processing modules 10 serve as a protection function that is sensitive to the real-time core running time, and a plurality of mutually isolated hierarchical protection virtual containers 21 serve as protection functions that are insensitive to the running time, and are particularly suitable for hierarchically protecting application environments of a middle-substation domain layer and a wide-area layer. Therefore, the hierarchical protection system 100 based on the virtual container in the embodiment of the present invention can efficiently process the fast and slow services (without the delay protection function and with the delay protection function) in the hierarchical protection, and has a good degree of adaptability, thereby simplifying the structure of the current hierarchical protection system 100, reducing the complexity and the construction and maintenance cost of the hierarchical protection system 100, and improving the maintainability and expansibility of the relay protection system without changing the superior relay protection performance of the hierarchical protection.
In a specific embodiment, the data exchange processing modules 10 are further configured to, when the local layer protection fails, execute a station domain redundancy non-delay differential protection function, and send corresponding SV data and GOOSE packets to the corresponding hierarchical protection virtual container 21, so that the hierarchical protection virtual container 21 executes a delayed backup protection function in the station domain layer protection and the wide area layer protection.
It can be understood that the in-situ layer protection may be single-interval protection such as line protection, capacitor protection and the like, or cross-interval protection such as bus protection, transformer protection and the like. Correspondingly, the in-situ layer protection device comprises a data sampling module and an intelligent terminal, wherein the data sampling module is used for collecting data of a protected object, and the intelligent terminal close to the protected object completes an action outlet so as to realize in-situ layer protection.
In the embodiment of the present invention, a plurality of data exchange processing modules 10 are respectively connected to each in-situ layer protection device. When the in-situ layer protection of any in-situ formation protection device fails, for example, the sensor of the data sampling module fails and cannot continue to acquire the data of the protected object, the corresponding data exchange processing module 10 executes the station domain redundancy non-delay differential protection function to control the intelligent terminal close to the protected object to complete the action exit. Therefore, the hierarchical protection system 100 in the embodiment of the present invention can also perform real-time nuclear-operating station domain redundancy non-delay differential protection quickly when in-place layer protection failure occurs, so as to remove a fault without affecting the rapidity of the system, and the system reliability is high.
In addition, the real-time core provides corresponding data to the hierarchical protection virtual container 21 for delayed backup protection processing, and the master control management module 20 has strong CPU performance, which can meet the calculation requirement of backup protection of a plurality of hierarchical protection virtual containers 21. Therefore, the hierarchical protection system 100 based on the virtual container in the embodiment of the present invention can efficiently process the fast and slow services in the hierarchical protection, and has a good degree of matching.
In a specific embodiment, the hierarchical protection virtual container 21 runs in a virtual container mirror space 21a in the master management module 20, and each of the hierarchical protection virtual containers 21 is connected to the corresponding data exchange processing module 10 through a communication channel.
