Two Stages

Research of stability of the power systems (PS) assumes the analysis of stability static or dynamic both generators, and engines. This article represents creations of the PS mathematical model is considered as sequence of two stages: creation of models of separate elements; creation of model of their interaction. The mathematical description of a site of distributive system on the example of the synchronous generator.

Node Voltage

Traditional power flow calculation can only supply the information of the conventional electric parameters, such as node voltage, branch current, power, etc. The transmission of power which is injected into the network by each power source, including power supply paths, power belongs, relationship among the power injected into each nodes, cannot be given. To solve this problem, this paper using the theory of the physical distribution of power network’s energy, proposes a matrix method for describing the power transmission, expresses the value and supply paths of the power from each single source in power network with the analytic method.

Grounding System

With the rapid development of power network automation, the detection of the default single-phase grounding fault line in small current neutral grounding system has became a hot spot in research of power network system. Generally, power network neutral point is not grounded or grounded through arc-suppression coil grounding. When single phase grounding fault occurs, the power network system is named as small current grounding system since the grounding short-circuit is small due to a low-impedance short circuit.
