1 Scope

This standard describes the operating conditions and typical characteristics of active-fed converters (AIC) using various technologies and topologies, which can be connected

Between the AC side of the power supply network (grid) and the DC side with constant current or voltage, and perform electrical power in both the forward and reverse (feedback) directions

Rate (active and reactive) transformation:

Generally, active-fed converters are compatible with all voltage and power levels of variable speed electric drive systems (PDS), uninterruptible power supply systems

(UPS), active filters, photovoltaic systems, wind power generation systems, battery-supported power management systems, etc: are used together on the DC side:

Active-fed converters are usually connected between the power supply network (AC side) and the DC side of current or voltage: The purpose is to synthesize sinusoidal

Wave AC current to avoid generating low frequency harmonics (for example, the frequency is lower than 1kHz): Some of them can also compensate for the existing

Harmonic distortion: Moreover, they can regulate the power supply network by transferring electrical power (active and reactive) in both the forward and reverse (feedback) directions

This can save energy and stabilize the power supply voltage in the system, or couple renewable energy or electrical energy storage devices with the power supply network:

This standard provides practical methods for analyzing the emission values of active-fed converters in power supply networks: The method is based on 2kHz~9kHz frequency

The latest results of section line impedance values and the withstand capability of capacitors directly connected to the power supply network:

This resulted in basic considerations for the design of emission values below 150kHz:

The following content is outside the scope of this standard:

--- Active feed application design, development or further functional requirements;

--- Parasitic components in the facility or poor electronic design and their treatment measures cause the active feed converter to interact with other equipment

The possibility of use or influence;

---"Overhead line" power supply network: lack of information (measurement) of its three-phase impedance: This may be the subject of a future version:
