and community applications, ocean energy conversion devices require close attention to the power quality of their output: inferior electricity may have a negative impact on the power supply and load: Therefore, there is a need to develop guidelines to reduce the burden on manufacturers, research designers, and users on device design, Power quality issues during use: Electrical system planners also need to determine the grid connection requirements for such variable intermittent energy sources while maintaining Maintaining its high reliability and high power quality standards: In other renewable energy and traditional energy power generation fields, power quality is a mature topic and relevant standards already exist: But the ocean energy power generation system There are no standards or technical specifications for power quality and grid connection requirements: Therefore, it is necessary to gradually and collaboratively develop detailed standards to solve this problem: This document is intended to: ---Identify single-phase/three-phase, grid-connected/off-grid (including microgrid) power based on wave, tidal current and other water flow energy conversion devices System power quality issues and parameters (including non-equipment specific parameters and non-normative parameters); ---Establish guidelines for measurement methods, application techniques and result interpretation: In addition to containing relevant definitions, normative references, symbols and units, tables, appendices and other supporting material, the core content of this document is Will include the following main contents: ---Identify characteristic parameters, define and clearly characterize the parameter values required to characterize the power quality impact of ocean energy conversion devices; ---Develop measurement procedures related to ocean energy conversion devices; --- Develop standardized procedures for measuring characteristic parameters, including test and measurement conditions and test equipment requirements: This document will provide device developers and applied researchers with guidance for assessing the power quality of ocean energy conversion devices: Power quality requirements for ocean energy conversion devices1 ScopeThis document specifies the definition and measurement procedures of power quality characteristic parameters of ocean energy (wave energy, tidal energy and other current energy) conversion devices: and assessment methods: content include: a) Definition and quantitative description of the power quality characteristic parameters of ocean energy (wave energy, tidal energy and other water flow energy) conversion device units; b) Measurement procedures to quantify the characteristic parameters of ocean energy (wave energy, tidal energy and other current energy) conversion devices: The measurement procedure is suitable for single ocean energy conversion devices or power plants with three-phase grid-connected or off-grid connections: This document only requires that it can be transferred in the ocean Test at the common coupling point of the medium voltage or high voltage system of the switching device and evaluate it in accordance with the provisions of this document: The measurement procedures are applicable to marine vessels of any capacity: Foreign energy conversion device: This document describes simple measurement and reporting procedures for ocean energy conversion devices connected to the low voltage grid: Design of medium voltage and low voltage connections is defined as: a) Medium-voltage connected units usually refer to parallel three-phase ocean energy converters operating in offshore power plants and transmitting power through high-voltage or medium-voltage grids: Replace device; b) Low-voltage connected units usually refer to single-phase or three-phase marine energy transformers that supply small-scale loads in grid-connected, off-grid or microgrid systems: Replace the device: Considering that ocean energy is an emerging energy source, this document still has the following limitations: a) Only the voltage fluctuation under continuous operation is considered, and the voltage fluctuation during switching operation is not considered yet; b) For the specific classification of measured flicker values, the different resource categories given in this document should be used as guidance and suggestions, and users should use them with caution These resource categories: Measurement procedures need to increase the possibility of designing according to non-site-specific requirements to ensure that the same ocean energy conversion device is used: Under the conditions of configuration and operation mode (such as control parameters), the power quality characteristics of a certain test site are also applicable to other sites: If it matches If any changes in settings or operating modes cause changes in the power quality of the ocean energy conversion device, it will be evaluated separately: This document is applicable to the measurement of wave energy, tidal energy and other water flow energy conversion devices, and includes the electrical energy of ocean energy conversion device power plants: Useful information for quality testing: This document does not apply to Ocean Thermoelectric Energy Conversion Devices (OTEC):2 Normative reference documentsThe
