This section refers to the dynamic performance of its characteristic frequency or time domain transient conditions to cover the range of steady-state conditions between events and phenomena. It involves dynamic performance should fall under steady-state or transient conditions, both ends of the HVDC system is connected with the AC system or its components, such as power plants, interaction between reactive sources, etc., exchange lines and buses. Both ends of the HVDC system uses a three-phase bridge connection (dual) consisting of 12-pulse (wave) inverter unit structure, with two-way power transmission capability. Inverter using the metal oxide surge arresters without gaps insulated thyristor valves with a leg. This section does not consider the commutation diode valve. Although not specifically mentioned for multi-terminal HVDC systems, but many of the elements in this section also applies to multi-terminal systems. GB/Z 20996 consists of three parts. Steady Part 1, Part 2 failures and operational, Part 3 dynamic. In the formulation and preparation process has three parts to avoid a repeat. Therefore, when the user intends to develop HVDC ends specifications, the entire contents of the three reference parts. The various components of the system, should pay attention to the difference between the system and equipment design and performance specifications between norms. This section does not provide equipment specifications and test requirements. But rather focuses on the technical requirements that affect system performance.

GB /Z20996.3-2007/IEC /TR60919-3.1999IntroductionIn the construction of China's power grid, HVDC transmission has a very broad development prospect for long-distance power transmission and large-area networking. An important means to solve high voltage, large capacity, long distance power transmission and asynchronous networking. According to the actual needs of China's HVDC project and high voltage straight The development of the trend of the power transmission technology is based on the digestion and absorption of imported technologies, the construction experience of domestic DC transmission projects and the independent development of equipment. On the basis of research, the national standard system for HVDC transmission equipment was developed. Content includes basic standards, master equipment standards, and control and protection equipment standard. The project has completed or is in the process of developing a total of 19 national standards. (1) "The first part of the performance of the high-voltage DC system" (2) "The second part of the performance and performance of the high-voltage DC system" (3) "The third part of the performance of high-voltage DC system" (4) "Insulation coordination procedure for HVDC converter station" (5) "Determination of loss of high-voltage DC converter station" (6) "Conversion transformer for the second part of high-voltage direct current transmission" (7) Technical parameters and requirements for oil-immersed converter transformers for HVDC transmission (8) "Oil-immersed smoothing reactor for HVDC transmission" (9) Technical parameters and requirements for oil-immersed smoothing reactors for HVDC transmission (10) "Guidelines for Non-Gap Metal Oxide Arresters for HVDC Converter Stations" (11) "Parallel capacitors and AC filter capacitors for HVDC transmission" (12) "DC Filter Capacitor for HVDC Power Transmission" (13) "General requirements for ordinary thyristors for HVDC transmission" (14) "Test of Thyristor Valves for Power and Electronic Technology Static Reactive Power Compensation Devices for Transmission and Distribution Systems" (15) "HVDC power transmission system control and protection equipment" (16) "High-voltage DC converter station noise" (17) "High-voltage DC bushing technical performance and test methods" (18) "General Requirements for Photo-Controlled Thyristors for HVDC Transmission" (19) "Guidelines for DC System Research and Equipment" GB /Z20996.3-2007/IEC /TR60919-3.1999 High-voltage DC system performance Part 3. Dynamic1 ScopeThis part of GB /Z20996 provides comprehensive guidelines for the dynamic performance of high voltage DC systems. The dynamic performance in this section refers to its special features. The frequency or time region covers events and phenomena ranging from transient conditions to steady state conditions. The dynamic performance it relates to should be stable Under the transient or transient conditions, the high-voltage direct current transmission system at both ends and the connected AC system or its components, such as power plants, AC lines and busbars, reactive power sources The interaction between the two. The high-voltage direct current transmission system at both ends adopts a 12-pulse (wave) converter consisting of three-phase bridge wiring (dual) The component is composed of two-way power transmission capability. The inverter is made of a thyristor valve that is insulated and fitted by a gapless metal oxide arrester. For the bridge arm. Diode converter valves are not considered in this section. For the multi-terminal HVDC transmission system, although not specifically mentioned, but in this section Multiple content is also available for multi-end systems. GB /Z20996 consists of three parts. Part 1 is steady state, Part 2 is fault and operation, Part 3 is dynamic. In the development and editing During the writing process, it has been avoided to repeat the three parts. Therefore, when the user prepares to prepare the specifications of the high-voltage DC system at both ends, Test the entire contents of the three parts. Pay attention to the differences between system performance specifications and equipment design specifications for each component in the system. This section does not specify equipment technology The technical conditions and test requirements, but focus on those technical requirements that affect the performance of the system. This section also does not include detailed seismic performance requirements. begging. In addition, there may be many differences between different HVDC systems. This section does not discuss this in detail. Therefore, this section should not Directly used as a technical specification for a specific engineering project. However, based on this, the specific transmission system can be programmed to meet the actual system. Technical specifications required by the system.
