What is PD IEC TS 62600-30- Electrical power quality requirements about?
The IEC 62600 series covers marine energy, including wave, tidal, and other water current converters. PD IEC TS 62600-30 is the 30th part in the series that specifies the definition and specification of the quantities to be determined for characterizing the power quality of a marine energy (wave, tidal and other water current) converter unit and measurement procedures for quantifying the characteristics of a marine energy (wave, tidal and other water current) converter.
The measurement procedures are valid for a single marine energy converter (MEC) unit (or farm) with three-phase grid or an off-grid connection. The measurement procedures are valid for any size of MEC unit, though PD IEC TS 62600-30 only requires MEC unit types intended for PCC (Point of Common Coupling) at Medium Voltage (MV) or High Voltage (HV) to be tested and characterized.
The measurement procedures are designed to be as non-site-specific as possible so that power quality characteristics measured at a test site, for example, can be considered valid at other sites also providing the same MEC unit configuration and operation modes (for example control parameters). If the configuration or operation mode is changed in any way that might cause the MEC unit to behave differently with respect to power quality, the power quality measurement procedures must be repeated.
PD IEC TS 62600-30 is for testing of wave, tidal and other water current energy converter units, though it contains information that may also be useful for testing of MEC farms.
Who is PD IEC TS 62600-30- Electrical power quality requirements for?
PD IEC TS 62600-30 on marine energy. wave, tidal, and other water current converters are useful for:
- Marine energy converter device manufacturers
- Entities involved in hydraulic energy engineering
- Operators of marine energy converters
- Operators of marine energy test sites
- Electrical system planners or regulators
- Certification bodies
- Regulatory bodies
Why should you use PD IEC TS 62600-30- Electrical power quality requirements?
Marine energy conversion systems, as viable electric power sources for utility and community-based applications, require close attention to the quality of the power produced. Poor power quality has negative impacts on both the electrical power source and the load.
PD IEC TS 62600-30 aims at:
- Identifying power quality issues and parameters (non-device specific and non-prescriptive) for single/three-phase, grid-connected/off-grid (including micro-mini grid) marine wave, tidal and other water current converter-based power systems
- Establishing the measurement methods, application techniques and result-interpretation guidelines
In addition to containing the associated definitions, normative references, symbols and units, forms, annexes, as well as other supporting material, the core of this technical specification contains the following key items:
- Identify characteristic parameters, define and specify the quantities required to characterize the power quality impacts of marine energy conversion devices
- Develop measurement procedures as pertains to marine energy devices
- Outline standardized procedures for measuring the characteristic parameters, including test and measurement conditions, and test equipment requirements
As a result, PD IEC TS 62600-30 provides guidance for the manufacturer, developer and user on how to mitigate power quality issues during the design of the device. Electrical system planners can also identify the requirements for grid integration of such variable and intermittent energy sources, while maintaining high reliability and power quality standards.
