Abstract ▼ AI-Helper

This paper scrutinized the damping effects of installing the prototype PSSs by a transient analysis for eight buses of faults in the South Korean power system. The PSSs used have the co-PSS blocks for IEEEST model with a single input and the co+power PSS blocks for PSS2A model with dual inputs. The simulation tool was a TSAT(Transient Security Assessment Tool) developed by Powertech Labs Inc. The voltages of the transmission line for simulations were 765kV and 345kV, and the faults for eight cases were sequenced by considering the open state and the close state of the lines. In the simulations, the three-phase line to ground (L-G) fault generated different points for each region. The simulations were compared to the cases of no PSS, partial IEEEST and PSS2A, absolute IEEEST, and absolute PSS2A to show that the power system oscillation can be effectively damped by PSS modules. Simulations were conducted to confirm the effectiveness for the KEPCO (Korea Electric Power Corporation) power system.

가설 설정

4.3(a) oscillated significantly. The bus terminal voltages in Fig.
The forms of the PSS that apply to the Korean power system are the IEEEST and PSS2A types. First, the IEEEST type uses an angular velocity G)only by input. As the name implies, the speed based power system stabilizer relies on the measurement of the generator shift speed for generating the stabilizing signal.

제안 방법

Four types of PSSs were applied for the case study. However, not all attached PSSs were applied to every generator.
In this paper, we examined 8 cases of faults to demonstrate the damping effects produced by IEEEST type and PSS2A PSS in Korean power systems in 2005. Results to apply and to examine by applying the PSSs are as follows:
Power system stabilizers (PSSs) aid in maintaining power system stability and in improving dynamic performance by proving a supplementary signal to the excitation system. The evaluation of power system security investigates the ability of the switching actions and the circuit breaker operation of power equipments under continuous system operation such as disturbances for the circuit fault. That is, whether thermal overloads, voltage and current, etc.

이론/모형

In this paper, the transient stability problems of a power system stabilizer (PSS) in the Korean power system were analyzed by using the TSAT (Transient Security Assessment Tool) program. The PSSs were the IEEEST and the PSS2A [13], [14].
