Abstract

The invention discloses a wind turbine generator set converter power compensation method and device and a converter. The method comprises the following steps: obtaining the current network side powersetting value and the current network side power actual value of the network side power of the converter; judging whether the network side power reaches the full power state based on the current network side power actual value and obtaining the judgment result; determining the current network side power compensation value of the network side power according to the judgment result; and determiningthe current machine side power setting value of the machine side power of the converter based on the current network side power compensation value and the current network side power setting value. Therefore, the current machine side power setting value can be dynamically adjusted so that the current network side power actual value can accurately meet the real-time dispatch requirement of the powergrid after the machine side power is subjected to nonlinear loss.

Description

Technical field [0001] The present invention relates to the technical field of wind power generation, in particular to a power compensation method, device and converter of a wind power generator set converter. Background technique [0002] As people pay more and more attention to environmental protection, wind power generation has been widely welcomed by the public because of its clean and pollution-free characteristics. figure 1 Shown is the block diagram of the existing permanent magnet direct drive wind turbine system. Such as figure 1 As shown, the system includes: a permanent magnet syancronus generator 100 (permenet magnet syancronus generator, PMSG) and a converter 200. The converter 200 feeds the generated electric energy into the grid 300. Among them, the converter 200 includes: a rectifier converter 201 and an inverter converter 202. The system mainly has the following two operating modes: grid dispatch mode (0 mode) and maximum power tracking mode (1 mode). Among th...
