Abstract

The invention discloses a wind farm AGC (auto gain control) functional test system and a test method thereof. The test system includes a PC machine, a wave record triggering unit and a data acquisition unit that are connected sequentially, wherein the PC machine is connected with a wind farm monitoring system / wind turbine energy management platform through a network interface. The system provided by the invention has complete functions and high automation degree, does not need manual intervention, and has excellent expansibility; an active power curve issuing tool of the system provided by the invention can be arranged at a power network dispatching center, is communicated with an EMS system through the network, and issues the wind field AGC control object, and the wave record triggering unit and the data acquisition unit are equipped on the wind farm side at the time for recording the real-time data of the wind farm during regulation and control; and a control interface is supplemented and perfected, the system provided by the invention has the tested capacity of AVC (auto voltage control).

Description

Technical field [0001] The invention relates to the field of new energy, in particular to a wind farm AGC function test system and a test method thereof. Background technique [0002] At present, compared with conventional power sources, wind farm systems still have problems in power prediction, frequency modulation, peak shaving, voltage / reactive power control, low voltage ride-through, etc., which are difficult to meet the requirements of large-scale applications and achieve predictable wind power , Schedulable and controllable goals still need a long way to go. In addition to relying on the advancement of wind turbine design and manufacturing technology to solve the above problems, the improvement of grid dispatching, analysis and control is also a very important aspect. [0003] AGC (Automatic Generation Control) is one of the paid auxiliary services provided by grid-connected power plants. The generator set tracks the output target command issued by the power dispatching cent...
