Real-time Simulation Study on Stability-improving Effects of Superconducting Generator in Power Systems by use of Digital Type Generator Model and Analog Type Power System Simulator.

Enhancement on Available Transfer Capability of Multi-machine Power System by Introduction of Superconducting Generator

“…1. Outline of the simulation equipments and computation procedure of digital type SCG model (5) are not presented here.…”

“…Superconducting Generator (SCG) with advantages of small size, low impedance and so on may bring many good properties to the existing power systems. Many experimental and digital simulation researches have confirmed the improving-effect of SCG on power system ability such as transient and voltage stabilities enhancement, high generation efficiency, enlargement of available operating range, etc (1)- (5) . However, few studies have been done for investigating the impact of SCG on ATC (Available Transfer Capability) of power system, which is considered to be one of the key parameters for open transmission access power systems.…”

“…In this paper, real-time simulation with a 5-machine infinite bus model power system has been done to investigate the difference between the ATC in cases of SCGs (with different generator constants) and that in case of the conventional generator (CG). The realtime simulation is conducted by use of an existing analog type real-time power system simulator and a digital type SCG model, which is developed by the authors (5) and be suitable for accomplishing real-time simulations while generator constants and its control systems change frequently. Real-time simulation results have verified the good virtue of SCG on improvement of ATC and illustrated the advantage of SCG over CG from the point view of ATC enhancement.…”
