“…State space node method. Since it is possible to observe the amount of electricity that cannot be measured in a live power system due to technical requirements, the simulation results are helpful to analyze the impact of the transient (abnormal) state of the power system operation and also provide valuable data [10] . If you want to use a computer to realize system simulation, it is necessary to convert a continuous model to a discrete model.…”

Digital electromagnetic transient simulation is an important means to analyze the operation, planning and control of power systems. Numerical integration algorithm is the core of electromagnetic transient simulation analysis. By analyzing the existing electromagnetic transient simulation methods of power systems, it is difficult to solve the numerical oscillation and decoupling problems, and the root matching method is proposed to solve such problems. From the perspectives of basic component modeling methods and basic simulation algorithms, the disadvantages of mainstream algorithms in solving electromagnetic oscillations are analyzed. Combining the calculation and simulation features in FPGA, the three-phase two-level inverter model of the power system built is verified.

“…In [12] the average value method was used to calculate the output value of a three-phase interleaved converter. In [3,[13][14][15][16][17][18][19], equations are used in the state space to describe the behaviour of different topologies of power converters. However, in order to be implemented, an FPGA with wide range of resources is required; around 65000 Look Up Tables (LUT) to obtain a step size of the order of 5ns, in some cases multiplex arithmetic operations can reduce the size between 15000 and 6000 LUT, with a cost of increasing the step size to 250 ns [18] In this article, the model based on Switching Functions (SF) for a Dual Interleaved Buck-Boost Converter (DIBBC) with interphase transformer (IPT) was developed, and the hardware implementation was made for an FPGA of limited resources.…”

Under the unavailability of some components of a complex system, the Hardware In the Loop (HIL) tool allows the emulation of other subsystems. When these devices are not available, a customized emulator can be developed based on the Piecewise Linear Model (PWLM) and a numerical method for solving the differential equations system. However, these implementations require the use of a Field Programmable Gate Array (FPGA) with extensive hardware resources. In this article we propose the use of switching functions for the modeling of power converters of a Hybrid Power System (HPS), allowing the reduction of hardware resources of the FPGA, and the number of steps per switching cycle is increased. The results are compared with SABER simulations and a PWLM evaluated with the Euler method.

“…In the early 1990s, a switch model that keeps the network equations fixed regardless of switch statuses was proposed [11], [12]. The fixed-matrix modelling approach has successfully been implemented on FPGA [6], [8], [13], but it is known to introduce false numerical transients due to its convergence process that restricts its operation at high switching frequencies [14].…”

The realm of Hardware-in-the-Loop (HIL) simulation resorts to Field Programmable Gate Arrays (FPGAs) to achieve time-steps below 1 µs. Such low time-steps are of importance for the aerospace and automotive industries, where power converters have their switching frequencies in the 10-200 kHz range. This article proposes a Network Tearing Technique (NTT) that allows subsets of switches to be treated independently, alleviates embedded memory requirements, and reduces the computational burden. An iterative algorithm is used to determine the state of naturally commutated switches, thus offering a realistic model of the power converter, independently of its operation mode or topology. A Gauss-Jordan processing unit is implemented to solve interface voltages/currents from the torn circuit. Custom floating-point operators are used to ensure good accuracy, high frequency operation as well as low computational latency. A neutral-point-clamped (NPC) converter case study is presented to demonstrate the effectiveness of the method. Simulation results are validated against a reference model at a 750 ns time-step and 30 kHz Sine Pulse Width Modulation (SPWM) switching frequency.
