The invention provides a photovoltaic electric field data analysis and real-time environmental monitoring-based active power control system. The system includes a system modeling predictive control subsystem, a data acquisition subsystem, a data storage subsystem, an electric field control subsystem and a control effect feedback subsystem. The system can play a key role of reference for the daily regulation of an electric field and can effectively improve the safety level of the operation of the electric field and improve the quality of the electric energy of the electric field; and the formulation of a specific control algorithm for each electric field can be actually realized.
Description
technical field [0001] The invention belongs to the field of active power control systems, in particular to an active power control system based on photovoltaic electric field data analysis and real-time environment monitoring. Background technique [0002] According to the "Photovoltaic Power Generation Briefing in the First Half of 2015" released by the National Energy Administration, in the first half of 2015, the country's newly added photovoltaic power generation grid-connected capacity was 7.73 million kilowatts. Photovoltaic power generation is facing a new "spring of development". But the photovoltaic power generation industry is also facing a huge challenge: due to power quality problems, it is difficult to connect to the grid. Power quality problems are mainly caused by the communication system on the electric field side, unit status, control system, weather and other factors. However, the existing active power control system considers relatively single factors a...
