Distributed power supply intelligent control device

Abstract

The invention discloses a distributed power supply intelligent control device which comprises a distributed power supply system and a power grid, the power grid is composed of a high-voltage network, a medium-voltage network and a low-voltage network, and transformation transmission circuits are arranged between the high-voltage network and the medium-voltage network and between the low-voltage network and the medium-voltage network. According to the invention, redundant energy is merged into a power grid through a plurality of distributed power supply systems, a reactive compensation module is arranged to compensate unstable voltage in a high-low voltage distribution line of a grid-connected circuit, and the stability of merged current of the grid-connected circuit is monitored in real time, so that the grid-connected circuit is interrupted when a certain parameter is abnormal; functions of automatic acquisition, signal conditioning, analog-to-digital conversion and data preprocessing of state parameters of monitored equipment are realized, on-site digitalization and caching of the monitored parameters are realized, a monitoring result can be sent to a control terminal through a communication module according to needs, a power grid management master station is timely contacted, a fault is cooperatively checked, and the system is rapidly maintained. Therefore, the safety of the distributed power supply system is ensured, and the utilization efficiency of energy is improved.

Description

technical field [0001] The invention relates to the technical field of distributed power sources, in particular to an intelligent control device for distributed power sources. Background technique [0002] The energy crisis and climate deterioration have led to the rapid development of distributed power sources including photovoltaic power generation, wind power generation and other renewable green power sources (intermittent power sources). Distributed power sources such as photovoltaic power generation and wind power generation are non-polluting and rich in resources. They are photovoltaics that can best meet human needs. They can meet the growing demand for electricity and have great development value. [0003] Usually the distributed power supply is connected to the public power grid and supplies power to the load connected to the public power grid through the public power grid. When the public power grid fails or the power generation capacity of the distributed power su...
