IEC TS 62578-2015 电力电子系统和设备--有源助增变流器应用的操作条件和特性 Power electronics systems and equipment - Operation conditions and characteristics of active infeed converter (AIC) applications including design recommendations for their emission values below 150 kHz

This Technical Specification IEC TS 62578 describes the operation conditions and typical
characteristics of active infeed converters (AIC) of all technologies and topologies which can
be connected between the electrical power supply network (lines) a.c. side and a constant
current or voltage type d.c. side and which can convert electrical power (active and reactive)
in both directions (generative or regenerative). 
Applications with active infeed converters are commonly used with the d.c. sides of adjustable
speed power drive systems (PDS), uninterruptible power systems (UPS), active filters,
photovoltaic systems, wind turbine systems, battery backed power management systems etc.
of all voltages and power ratings.
Active infeed converters are generally connected between the electrical power supply network
(a.c. side) and a current or voltage d.c. side, with the objective to avoid emitting low
frequency harmonics (e.g. less than 1 kHz) by synthesizing a sinusoidal a.c. current. Some of
them can additionally compensate the pre-existing harmonic distortion of a given supply side
voltage. They are moreover able to control the power factor of a power supply network section
by moving the electrical power (active and reactive) in both directions (generative or
regenerative), which enables energy saving in the system and stabilizes the power supply
voltage or enables coupling of renewable energy sources or electrical energy storage devices
to the supply. 
A practical and analytical approach for emission values for AICs in power supply networks is
given, which is based on the latest results for line impedance values between 2 kHz and
9 kHz and withstand capability of capacitors connected directly to the supply. 
This results in design recommendations for emission values below 150 kHz. 
The following is excluded from the scope.
• Requirements for the design, development or further functionality of active infeed
applications.
• Probability of interactions or influences of the AIC with other equipment caused by
parasitic elements in an installation or caused by poor electronic design as well as their
mitigations.
• "Overhead line" power supply networks because of lack of information (measurements) of their three phase impedances. This could be the subject for future editions.dition 2.0 2015-04 TECHNICAL SPECIFICATION SPECIFICATION TECHNIQUE colour inside Power electronics systems and equipment – Operation conditions and characteristics of active infeed converter (AIC) applications including design recommendations for their emission values below 150 kHz Systèmes et équipements électroniques de puissance – Conditions de fonctionnement et caractéristiques des convertisseurs à alimentation active (AIC), y compris les recommandations de conception pour leur
