1. A method of testing an electrical system of a wind turbine, wherein the wind turbine comprises at least one power converter coupled to a generator of the wind turbine, the at least one power converter is operable in a power generating mode in which the at least one power converter provides a conversion of electrical power generated by the generator and provides a controllable output of AC electrical power towards a power grid, the method comprising:
operating the wind turbine in a testing mode, wherein the operating in the testing mode comprises:
decoupling the electrical system to be tested from the power grid;
operating the at least one power converter as a test condition generator;
supplying electrical power to the test condition generator;
converting, by the test condition generator, the received electrical power to generate predetermined electrical test conditions, and
exposing the electrical system to be tested to the predetermined electrical test conditions,
wherein the test condition generator controls one or more electrical characteristics of the electrical test conditions.
