And the stability of AC system is improved, suppress the fluctuation of AC system frequency and voltage, improve the stability of synchronization AC system
Energy.Transverter is the Core equipment of flexible direct current technology, modularization multi-level converter (modular multilevel
Converter, MMC) because it has the advantages that modularized design, switching frequency are low, harmonic performance is good turn into current flexible straight
Flow the preferred option of engineering.
Converter valve Control protection system is the tie of converter Control protection system and converter valve, receives converter Control guarantor
The instruction of protecting system and the control command that each submodule of each bridge arm is obtained after ovennodulation, referred to herein as downlink communication；Simultaneously
Gather the state of each submodule of converter valve and collect and send converter valve state in backward converter Control protection system, referred to herein as
Uplink communication.Said from control angle, the delay of up-downgoing communication is longer, and the stability margin of whole control system is lower；From protection
Angle says that the delay of up-downgoing communication is longer, and the sensitivity of converter valve excessively stream and overvoltage protection is lower, the margin of safety of converter valve
It is smaller.The delay and the framework of converter valve Control protection system are closely related, therefore should reduce the delay as far as possible.
At the same time, as industrial expansion and urbanization process, soil obtain more and more people's as scarce resource
Accreditation, at present in direct current and power electronics correlation engineering, soil turns into a key factor for restricting its development.It is meanwhile flexible
Direct current transportation application field is extended from transmission of electricity to application scenarios such as distribution, offshore platform, the power supplies of city multiterminal, above-mentioned application scenarios
Flexible direct current capacity is typically small, but has strict limitation to floor space, therefore, to adapt to soft straight densification development trend,
Converter valve Control protection system develops into a kind of trend toward compact direction.
The development trend of the converter valve Control protection system of static reacance generator is protected with the control of flexible direct current converter valve
The development trend of system is consistent.
Converter valve Control protection system framework common at present all comprises at least two layers, as shown in figure 4, i.e. each transverter
It is each to be responsible for transverter for one transverter level control unit of configuration and multiple bridge arm level control units, wherein transverter level control unit
Coordination between individual bridge arm, bridge arm level control unit are responsible for the coordination inside corresponding bridge arm.This framework does not meet converter valve control
The development trend of protection system processed, the delay of its relative individual layer framework that is delayed is longer, and each transverter configures multiple bridge arm level controls
Unit floor space processed is larger.
To adapt to the development trend of converter valve Control protection system, it is necessary to find a kind of converter valve Control protection system frame
Structure, the level of converter valve Control protection system is reduced, reduce device quantity, so as to realize the minimum of delay and volume, improved
The stability margin and margin of safety of transverter, improve the power density of transverter.
The content of the invention
