[Abstract]:With the development and maturity of power electronics technology, distributed generation technology and microgrid technology, more and more research on the power supply quality, microgrid control technology and energy dispatch among multi-microgrid has been carried out. The research on the reliability and flexibility of microgrid power supply is mainly focused on the control problem of distributed power converter in microgrid. The control strategy and its control algorithm become the key to the research. At the same time, with the continuous expansion of IEC61850 standard application, the interoperability of power electronic devices and their controllers in microgrid becomes more and more a development requirement. The combination of information communication technology and microgrid technology is of great significance to the exploration and construction of smart grid. In this paper, the control algorithm of converter is studied based on the IEC61850 standard and the example of microgrid interconnection. The content of this paper can be divided into two parts: (1) Information modeling and logical node design are the important foundation and prerequisite for the implementation of device interoperability. Taking the microgrid interconnected converter as an example, this paper analyzes three common control strategies of the converter, the design process of the PQ control algorithm and the design of the current control loop, and obtains the corresponding PQ control algorithm structure diagram. According to the structure diagram of the control algorithm, the information interaction model of the control algorithm is designed, and the specific interactive process of the information flow is analyzed. The functional logic nodes FPID and FSPT in the model, the arithmetic logic nodes FOPE0 / FOPE1 and FOPE2, and the commutation logic nodes, FABD and FDQA, are designed in detail. The design of logic nodes includes the design of input and output ports and the block diagram of algorithm implementation within the nodes. All logical nodes are instantiated, and the logical nodes are interrelated. Then the software phase-locked loop module, current control module and power control module are designed, and the relationship between the above modules and logic nodes is analyzed. Finally, the simulation model of PQ control is built on MATLAB/SIMULINK platform. The simulation verifies the functions of voltage phase locking, current following, active power and reactive power following, etc. The relationship between simulation waveform and logic node is pointed out. (2) the design of logic node can be applied to other examples. According to the design method of the above logic nodes, combined with the IEC61499 standard, taking substation bus interlock as an example, a logic function block based on IEC61850/61499 is designed through the specific mapping between IEC61850 model and IEC61499 model, and the function block is interoperable. Configurable and reusable. This paper mainly introduces CILO_FB and CSWIFB, designs the state machine and its algorithm in detail, and verifies the correctness of the function block. At the same time, it is convenient to design the whole bus interlocking system. Finally, the locking system is designed on FBDK platform and the correctness of the system is verified by simulation.
