Abstract

The invention relates to monitoring technique of a wind-solar complementary converter, and in particular relates to a monitoring device of the wind-solar complementary converter. The monitoring device of the wind-solar complementary converter solves the technical problems that storage capacity is small, searching is inconvenient, and a dynamic waveform display function is not possessed in an existing monitoring system of the wind-solar complementary converter. The monitoring device of the wind-solar complementary converter comprises a PC machine, and the PC machine is connected with a DSP control system which is connected with the wind-solar complementary converter; an SQL server database and a monitoring system are arranged in the PC machine; the monitoring system comprises four module that are a mode control module, a failure state module, a data report module, a real-time waveform module, a past-time waveform module and a variable management module. According to the innovation point of the monitoring device of the wind-solar complementary converter, based on the SQL server database technology, the storage function of the monitoring system of the wind-solar complementary converter is realized; consecutive storage of multi-screen data is realized, and the historical data are stored automatically; checking on the historical data is realized through the data report function; the function is played dynamically by the past-time waveform.

Description

technical field [0001] The invention relates to a monitoring technology for a wind-solar hybrid converter, in particular to a monitoring device for a wind-solar hybrid converter. Background technique [0002] As a renewable energy, wind energy has huge reserves and is non-polluting. As the capacity of wind turbines continues to increase, the cost of wind power generation will gradually decrease. It is the most promising renewable energy for large-scale development. As a core component of wind power equipment, wind power inverters have gradually entered the domestic wind power market. [0003] Wind-solar hybrid converters take advantage of the characteristics of strong sunshine during the day and strong wind energy at night in the western region, install wind turbines in the high-altitude area of ​​the wind farm, and arrange large-scale photovoltaic panels in the low-altitude area, so as to maximize the use of the geographical space of the wind farm and maximize the potential...
