Detection method and detection device of power fluctuation of wind power plant

Abstract

The invention relates to a detection method and a detection device of power fluctuation of a wind power plant. The detection method of the power fluctuation of the wind power plant comprises the following steps: acquiring data, analyzing data, storing data, monitoring and warning data. The detection method of the power fluctuation of the wind power plant is characterized by comprising the following steps: firstly analyzing data of maximum change rate of active power data in one minute and ten minutes according to data information obtained by acquiring data to respectively obtain the maximum power change rate of one minute and the maximum power change rate of ten minutes; storing data; then locally monitoring and displaying data and warning information; setting maximum power change rate alarm limiting value by the local monitor and generating alarm information. The detection method and the detection device can be used for quickly diagnosing failure state of the system; the detection method and the detection device take irreplaceable effects on the increase of reliability, safety and economical benefits of the wind power plant.

Description

technical field

[0001] The invention relates to a power fluctuation detection method and a detection device, in particular to a power fluctuation detection method and detection device for a wind farm. Background technique

[0002] With the gradual depletion of energy sources such as coal and oil, human beings pay more and more attention to the utilization of renewable energy. As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge, and the global wind energy is about 2.74X10 9 MW, of which the available wind energy is about 2X10 7 MW is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. China's wind energy reserves are large and widely distributed. The wind energy reserves on land alone are about 253 million kilowatts. my country's wind power development started relatively late, but with the encouragement and support of national policies, ...

Embodiment

[0020] The wind farm power fluctuation detection device includes a server end, a client end, a communication management machine, a background data center and data acquisition equipment. Such as figure 1 Shown is a data flow diagram of the wind farm power fluctuation detection method and detection device of the present invention. Collect and monitor data equipment, and forward the collected data to the server and local monitoring through the communication management machine to real-time data and alarms. If the device has an RS232 or 485 interface, the data acquisition device uses NPort for interface conversion to complete data acquisition. The server side includes a network communication service module and a data service module. The network communication service module serves as the server end to receive the network data of the communication management machine. The network communication service module is connected with the communication management machine through the TCP / IP ...
