Abstract:
At present, the demand for small-capacity grid-connected photovoltaic system is growing, because it reduces the cost of storage systems. The article focuses on analyzing the voltage quality of small-capacity grid-connected photovoltaic system in low voltage distribution networks at yard of Quang Tri Branch – Hue University, Viet Nam. The analysis proceeds over dark time, when the system consumes electricity, and over light time, when the system put electricity into the grid. Analysis results indicate that system parameters has match the requirements and the emergence of small-capacity grid-connected photovoltaic system contributes to improving the total harmonic distortions of low-voltage network.

Abstract:
For buildings and other constructions, fire protection is a must. The fear of uncontrolled fires and the desire to avoid their consequences is as ancient as human civilization. This fear has obvious enduring roots: unwanted fire is a destructive force that takes many thousands of human lives and destroys large quantities of asset. The primary objective of fire protection is to limit loss of properties and lives in the event of unexpected fires. Active fire protection is effective and efficient in most situations. However, passive fire protection, which includes the use of fire-proofing materials, provides an on-site fire resistance measure to prolong the longevity of load-bearing structures. Certainly, the nature, causes and scope of such events have changed considerably over millennia but fear and avoidance have remained as a primary human reaction and as an important human objective, respectively, for virtually every society. This paper will discuss on risk posed by fire, the passive fire protection components, conventional protection materials and thermally reactive materials. From the review, it can be concluded that Active fire protection is effective and efficient in most situations passive fire protection, which includes the use of fire-proofing materials, provides an on-site fire resistance measure to prolong the longevity of load-bearing structures.

Abstract:
The article analyzes the system information as a particular type of information, describing complex systems. It is shown that system information can only exist in complex systems with the property of emergence. The work describes the basic formal descriptions of complex systems. This article describes the evolution of the linear description of complex systems. The article contains set-theoretical descriptions of complex systems. Descriptions of complex systems, including system information explicitly, have been obtained. The article provides insight into the contents of the system information. The article introduces the definition of system information.
