Description

一种适用于电磁暂态多时间尺度实时仿真接口的实现方法Method for realizing electromagnetic transient multi-time scale real-time simulation interface 技术领域Technical field
本发明涉及一种实现方法，具体涉及一种适用于电磁暂态多时间尺度实时仿真接口的实现方法。The invention relates to an implementation method, in particular to an implementation method suitable for an electromagnetic transient multi-time scale real-time simulation interface.
背景技术Background technique
电力系统中，为了验证新的电力自动化设备的功能和性能，在设备投入实际系统运行前需要进行大量测试。电力系统实时数字仿真系统可以实时模拟电力系统各种运行工况，具有体积小、功耗低、通用性好、可重复性强、价格较动态模拟和数模混合式仿真装置低廉等优点，因而在电力自动化设备的测试中获得了广泛应用。In the power system, in order to verify the function and performance of the new power automation equipment, a large number of tests are required before the equipment is put into actual system operation. The real-time digital simulation system of the power system can simulate various operating conditions of the power system in real time, and has the advantages of small size, low power consumption, good versatility, high repeatability, low price dynamic simulation and low cost of digital-analog hybrid simulation device. Widely used in the testing of power automation equipment.
小步长仿真系统是一个完整的电磁暂态仿真系统的重要组成部分。随着仿真步长变小，系统的仿真负担也随之增加，从而需要使用FPGA硬件加速平台用以实现小步长仿真系统的实时的双精度浮点运算。The small step simulation system is an important part of a complete electromagnetic transient simulation system. As the simulation step size becomes smaller, the simulation burden of the system also increases, which requires the use of the FPGA hardware acceleration platform to implement real-time double-precision floating-point operations of the small-step simulation system.
但是由于仿真系统的仿真能力的限制，很多大型的仿真算例并不能完全在一个平台上运行。因此必须把大型的仿真算例划分为规模较小的网络，并通过接口互联，使得仿真结果与一个完整的大型仿真算例完全一致，而FPGA上只进行小步长仿真的局部网络。于是产生了在FPGA平台上进行多时间尺度分网并行仿真的需求。However, due to the limitations of the simulation capabilities of the simulation system, many large simulation examples cannot be run completely on one platform. Therefore, large-scale simulation examples must be divided into smaller networks and interconnected through interfaces, so that the simulation results are completely consistent with a complete large-scale simulation example, and only a small-step simulation local network is performed on the FPGA. This has created a need for parallel simulation of multi-time scale partitioning on the FPGA platform.
FPGA平台的设计必须保证三个原则：The design of the FPGA platform must guarantee three principles:
1.FPGA的程序应该实现保证并行，减少数据间的依赖关系。1. FPGA programs should implement parallelism and reduce dependencies between data.
2.FPGA为了提升仿真能力，应该缩短单一计算流水线的长度。2. In order to improve the simulation capability, FPGA should shorten the length of a single computing pipeline.
3.FPGA的LUT既可以用作存储又可以用于计算；为了提升FPGA的计算能力，必须减少FPGA的存储空间的使用。3. The LUT of the FPGA can be used both for storage and for calculation; in order to improve the computing power of the FPGA, the use of the storage space of the FPGA must be reduced.
现有的多时间尺度分网算法的设计方法利用了传输线自然延迟特性。其中，等值计算电路如图2所示，The existing multi-time-scale meshing algorithm design method utilizes the natural delay characteristics of the transmission line. Among them, the equivalent calculation circuit is shown in Figure 2.
电流源递推公式为：The current source recursion formula is:
Figure PCTCN2016089823-appb-000001
Figure PCTCN2016089823-appb-000001
由此递推公式可知，每一个子网上都需要保留2τmi/dt的变量，同时，由于τmi是一个变量，导致变量缓存区的大小不能固定；同时，上述递推公式中变量是模态量，交流的模态量转换为仿真系统需要的瞬时量，该转换是一个长流水线计算，会占用大量时序；最后，为了提升FPGA平台的仿真能力，必须尽量优化FPGA侧的计算，对于复杂的接口计算必须进行简化。From this recursive formula, it is known that each subnet needs to retain a variable of 2τ mi /dt. At the same time, since τ mi is a variable, the size of the variable buffer cannot be fixed. Meanwhile, the variable in the above recursive formula is modal. The quantity, the modal quantity of the AC is converted into the instantaneous quantity required by the simulation system. The conversion is a long pipeline calculation, which takes up a lot of timing. Finally, in order to improve the simulation capability of the FPGA platform, the calculation on the FPGA side must be optimized as much as possible for complex Interface calculations must be simplified.
