Embodiment Construction

[0037] The distributed power generation micro-grid control and power quality monitoring integrated equipment in the present invention receives the working status information of the on-site power generation unit through CAN or RS485, collects and calculates the power quality information through the measurement module, and uploads it to the central controller through Ethernet after collection and sorting . The central controller sends control commands to the monitoring integrated equipment through Ethernet, and after analyzing the control commands, sends commands through CAN, 485 or executes commands through input and output modules to complete the micro-grid optimization control process.

[0038] figure 1 It is a structural block diagram of a typical distributed microgrid control system. It demonstrates the connection method of typical monitoring and control integrated equipment and other units of the grid in distributed generation micro-grid. The distributed power generation...

Abstract

The invention relates to the field of intelligent micro-grids and aims to provide a distributed generation micro-grid control and electric energy quality monitoring integrated device and method. The device comprises a control and calculation module, an electric energy quality measurement module, a communication management module, an input and output interface module, an isolation circuit and a storage module. The control and calculation module comprises a calculation MCU and a control MCU; the electric energy quality measurement module comprises a voltage transformer, a current transformer, a signal processing circuit and a sampling circuit in a sequential connecting mode; the communication management module is connected with the calculation MCU in the control and calculation module, and the control MCU is connected with the communication management module, the input and output interface module and the storage module through the isolation circuit. The full-isolation circuit is adopted for performing optoelectronic isolation or electric isolation on all input and output signals of the device, the disturbance resisting capacity of the device is enhanced, and the device can be adaptive to usage on various micro power grid sites.

Description

technical field [0001] The invention relates to an integrated device for distributed power generation microgrid control and power quality monitoring, belonging to the field of intelligent microgrids. Background technique [0002] Microgrid refers to a small power generation system composed of distributed power generation units, energy storage devices, protection devices, energy conversion devices, related loads, control and monitoring systems, and is a system capable of self-control, protection and stable operation. The micro grid can not only operate in parallel with the large power grid, but also can operate in an isolated island. It is an important part of the smart grid. [0003] With the widespread application of micro-grid, micro-grid control and monitoring technology has become the focus of attention. Due to the great differences in the working principles and characteristics of the distributed generation units that make up the micro-grid, the control and monitoring m...
