Abstract

The invention discloses a testing platform and method generally used for the whole process of low voltage user side distributed power source grid connection. The testing platform comprises a distributed power generation simulation module, a power grid working condition generating module, a measuring analysis module and an isolation power distribution module, wherein the distributed power generation simulation module is used for simulating the output characteristic of distribution generation and is connected with the input end of EUT, the power grid working condition generating module is used for simulating the operation working conditions of multiple power grids and is connected with the output end of the EUT, the measuring analysis module is used for controlling the detection procedures and collecting data analysis detection results, and the isolation power distribution module is used for providing electricity for detecting equipment. The detecting method application of the whole process of the testing platform comprises the type test, the predelivery test, the dynamic simulation test and the field test of the EUT. The testing platform is designed in a modular combination mode so as to be integrated in a mobile vehicle trunk conveniently, modular equipment can be combined freely according to testing objects and testing modes to meet the requirement for testing under different occasions and environments, and the whole process testing of grid connection of low voltage distributed photovoltaic generators, wind power generators and gas turbine generators.

Description

technical field [0001] The invention relates to a general detection platform and method for the whole process of grid-connected distributed power supply on the low-voltage user side, and belongs to the technical field of distributed power supply. Background technique [0002] Distributed power generation refers to a small power generation system that is located near the user's location and makes full use of distributed resources for power generation. The power generation methods include distributed natural gas multi-supply, small and medium-sized hydropower, solar energy, wind energy, biomass energy, waste power generation, etc. The generated electricity is not only used by the user itself but also nearby, and the excess electricity is sent to the power generation facilities of the local distribution network, the power generation system or the multi-generation system with power output. Among them, distributed photovoltaics, wind power and distributed natural gas multi-supply...
