Models Comparison

As for transient stability simulation, Chinese researchers often use PSASP (Power System Analysis Software Package) as an auxiliary analysis tool while PSS/E (Power System Simulator for Engineering) is commonly used overseas. The correspondence of models contained in these two software packages will be discussed in this paper. Correspondent model parameters can be converted mutually based on the inner link of PSASP and PSS/E. Similar testing results of one standard IEEE case show that this data conversion method is primarily workable.

The major role of power system is voltage stability. It is required to plan properly and smooth operation and control. It presents a new approach of voltage stability improvement in IEEE 57 bus system using hybrid algorithm. The hybrid algorithm (PSO-MVO) is combination of PSO which is used for exploitation and MVO used for exploration. It is used in an uncertain environment. The FACTS device as STATCOM is connected in IEEE 57 test system to check for event of voltage stability improvement through power system analysis tool (PSAT) software. Once the ability of system goes through sudden loading, its stability gets affected. It desires compensation to boost voltage from disturbances. The varied operative condition while not used STATCOM in the system, used with STATCOM tuned by PSO-MVO algorithm are measured judge the performance of the projected system. The hybrid PSO-MVO technique is implemented in this paper to solve the proposed problem. The simulation results are obtained by PSAT software for 57 IEEE bus systems. The hybrid algorithm validates its effectiveness compare to individual PSO and MVO algorithm.

Leading phase operation of generator is an effective method for the control and regulation of voltage and reactive power of power system. The ability of voltage regulation for key buses by control of generator is presented in this paper. The PSD-BPA software - Power System Analysis Software Package (PSD-BPA) is introduced firstly. The management database for leading phase operation of generator is discussed. From the lagging phase operation to leading phase operation of generator, the change curves of voltage for main 500kV bus and 220kV bus are analyzed. The sensitivity on voltage regulation of each generator of leading phase operation is given. Based on the analysis of short circuit fault of power plant, the limit output power of leading phase operation of multi-generators is proposed. The leading phase operation of generator has many advantages, such as easy to operate, simple and feasible implement, and the actual operation is safe and reliable. The technique was worthy to be widely used.

The classic equal-area criterion (EAC) is of key importance in power system analysis, and provides a powerful, pictorial and quantitative means of analysing transient stability (i.e. the system's ability to maintain stable operation when subjected to a large disturbance). Based on the traditional EAC, it is common sense in engineering that there is a critical cleaning time (CCT); namely, a power system is stable (unstable) if a fault is cleared before (after) this CCT. We regard this form of CCT as bipartite. In this paper, we revisit the EAC theory and, surprisingly, find different kinds of transient stability behaviour. Based on these analyses, we discover that the bipartite CCT is only one type among four major types, and, actually, the forms of CCT can be diversified. In particular, under some circumstances, a system may have no CCT or show a periodic CCT. Our theoretical analysis is verified by numerical simulations in a single-machine-infinite-bus system and also in multi-machine systems. Thus, our study provides a panoramic framework for diverse transient stability behaviour in power systems and also may have a significant impact on applications of multi-stability in various other systems, such as neuroscience, climatology or photonics.
