Discusses the three-phase bridge (dual) joins the 12-pulse (move) change ends of HVDC system failures and transient performance flow unit composed of operation. HVDC system does not involve many-fold, but the ends of the parallel system is included in the inverter and parallel lines are discussed. Assume inverter thyristor valve as a bridge arm, using metal oxide surge arresters without gaps with insulation, and power can be bi-directional transmission. This section does not consider the diode valve. 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. This section also does not include detailed seismic performance requirements. In addition, different HVDC systems may exist many differences, there is no discussion in this section of this detail, therefore, this section should not be used directly as the technical specifications for a specific project. However, you can take this as a basis for the preparation of a specific transmission system to meet the technical specifications required by the actual system. Content in this section is no distinction between the user and the manufacturer's responsibility.

GB /Z20996.2-2007/IEC /TR60919-2.1991IntroductionIn the construction of China's power grid, high-voltage direct current 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 DC transmission 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 high-voltage direct current transmission equipment is formulated. Content includes basic standards, main 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.

Faults and operations1 General1.1 Scope This part of GB /Z20996 is a guiding technical document on the transient performance and fault protection requirements of high voltage DC systems. Discussed Three-phase bridge (dual) coupled 12-pulse (dynamic) commutation unit composed of high-voltage DC system faults and transient performance of operation. Not involved And multi-terminal HVDC transmission systems, but the parallel converters and parallel lines included in the systems at both ends are discussed. Assume that the inverter makes The thyristor valve is used as the bridge arm, and the gap-free metal oxide arrester is used for insulation coordination, and the power can be transmitted in both directions. This section does not Consider a diode valve. 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 Used directly 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. The technical specifications required.
