Control Strategy of Thyristors Switched SVCs with High Power Quality

In this paper, new static VAR compensators SVCs schemes for inductive and capacitive reactive power are developed. The provided schemes improve the flexibility and power system quality of SVCs by developing new circuit topologies with new control strategy of the reactive power. New circuit schemes are introduced for thyristors switched reactors TSR and thyristors switched capacitors TSC to design harmonic-free SVC with higher discrete number of reactive power levels. This paper provides the control algorithm and block diagram of the new SVCs schemes. The switching strategies of TSR and TSC are described and implemented. The new scheme of TSC requires special modifications to decrease transient effects and implementation of specific switching strategies to acquire SVC with high power quality indexes

Ecologically Oriented Forestry Development in Belarus in the Context of Climate Change

This brochure is a result of implementing Activity 3.1.4: Consultancy Services to Develop Strategies and Actions Plans for the Adaptation of the Belarusian Forestry Sector to Climate Change and to Implement the Principles of “Green Economy” under Contract № BFDP/GEF/CQS/16/25-26/17 dated October 23, 2017, within the Belarus Forestry Management Project (TFОA1173 GEF/World Bank). It incorporates conceptual approaches to forest management in Belarus in the context of weather and climate change observed in recent decades. The brochure addresses the ways of combating adverse climate change impacts on the forestry, the challenges of reforestation, afforestation and forest tending techniques in order to adapt them to climate change. The report includes analysis of contribution of the Belarusian forestry to climate change mitigation as concerns atmospheric carbon dioxide absorption by forests and its partial sequestration as phytomass carbon, soil organic carbon and other forest fund components. The “green economy” principles and criteria have been developed for the Belarusian forestry, the ways to promote them in the emerging “green economy” have been proposed. A new concept of sustainable forest management has been formulated, which is based on the climate-oriented strategy of forestry development
