According to the National Standards Committee, a batch of national standards will come into effect on April 1, providing standard support for guiding and regulating the development of emerging and future industries, promoting the upgrading of traditional industries, improving the quality of transportation and tourism services, and protecting consumer rights. The "Technical Requirements for Relay Protection of Photovoltaic Power Stations" specifies the general requirements, configuration requirements, setting requirements, and setting management requirements for relay protection in photovoltaic power stations. The "Technical Specification for Remote Monitoring of Distributed Photovoltaic Power Generation Systems" specifies the normal working conditions, system architecture, technical requirements, inspection and testing methods, as well as marking, packaging, transportation, and storage for remote monitoring systems of distributed photovoltaic power generation systems. The "Safety Regulations for Photovoltaic Power Stations" specifies the safety requirements for equipment, facilities, operation, and maintenance of photovoltaic power stations. The implementation of these three standards is conducive to further standardizing the relay protection, remote monitoring, and operation and maintenance of grid-connected photovoltaic power stations, supporting the safe and stable operation of the new power system, and promoting the high-quality development of the photovoltaic power generation industry. The "Centrifugal Pumps for Petroleum, Petrochemical, and Natural Industries" specifies the classification and naming, technical requirements, basic design, auxiliary equipment, and related requirements for centrifugal pumps used in the petroleum, petrochemical, and natural gas industries. The implementation of this standard helps to further enhance the manufacturing level of centrifugal pumps for petroleum, petrochemical, and natural gas industries in China and ensure product quality. The "Quality and Evaluation of Multimodal Transport Services" specifies the service principles, service guarantees, service requirements, and service quality evaluation for multimodal transport, clarifying the service quality evaluation indicators and their calculation methods. The implementation this standard is conducive to improving the service quality and level of multimodal transport and providing technical basis for relevant departments to carry out industry supervision and management. The "Service Quality Requirements for Sightseeing Boats" specifies the requirements for sightseeing boat services, including facilities, equipment, environment, reception services, commentary, service personnel, and service. The implementation of this standard helps to improve the service level and quality of sightseeing boat tourism, optimize the tourist experience, and is of great significance to the healthy development of sightseeing boat tourism. The "Technical Specification for Tea Supply Chain Management" specifies the general principles of tea supply chain management, supplier selection and management, procurement, processing, packaging, warehousing, transportation and distribution, and sales. The implementation of this standard is conducive to ensuring the quality level of the tea chain, improving the efficiency of tea supply chain management, and supporting the high-quality development of China's tea industry.
