一、Background
Power Conversion System (PCS) is the core equipment in the new energy grid
system. With the support of relevant policies, continuous technological
innovation has driven down the cost of power conversion system and the market
has grown rapidly. According to data from Interact Analysis, the global power
conversion system market have an installed capacity of 89GW in 2023, a
year-on-year increase of 64%. It is expected that the installed capacity will
reach 215GW in 2029, with a compound growth rate of 16%.
二、Test requirement
The performance of power conversion system greatly affects the power
quality of new energy grids and affects the life of energy storage batteries.
Therefore, the country has launched a series of standards and regulations to
strictly regulate the power output range, harmonic current, voltage and other
indicators of e power conversion system to ensure that they meet quality and
safety standards.
1. National standards
2. Test point
①In order to enhance product competitiveness and achieve energy
conservation and efficiency goals, manufacturers must conduct comprehensive
testing in accordance with relevant industry standards.
②Power conversion system has high requirements for signal quality in power
conversion and regulation. Harmonic problems may cause waveform distortion of
voltage and current in the power grid, thus affecting the normal operation of
other equipment. Harmonic testing can ensure that the power conversion system
meets relevant power quality standards in actual operation, which is crucial to
ensuring the stable production and operation of the power network.
