REACTIVE POWER COMPENSATION AND VOLTAGESTABILIZATION FOR WIND POWER IN A WEAK DISTRIBUTION NETWORK

One of the most promising alternate sources of energy is wind energy. Energy of the wind is converted to electrical energy in wind farms and is then connected to a weak distribution network to supply local loads. Most wind farms use induction generators for electricity generation. These induction generators draw excessive reactive power for their operation and this causes shortage of reactive power in the system and leads to voltage collapse. This problem is simulated on PSCAD/EMTDC platform. For static compensation, capacitor banks are used and for dynamic compensation, Static Var Compensators (SVCs) are used

Strategy-as-Power:Ambiguity, Contradiction and the Exercise of Power in a UK Building Society

'Strategy-as-practice (s-a-p) scholars have urged us to attend to the messy realities of strategy so as to increase the relevance of research for practitioners. This article, whilsts recognising the need to focus on what managers do, develops a critique of this literature. It argues that the s-a-p approach (Whittington, Jarzabkowski, Johnson, Balogun) and the earlier 'Power School' (Mintzberg, Pettigrew, Pfeffer) share much in common as both present power as the possession of management. This overstates the ability of managers to control others whilst understating the scope for resistance. Second, it asserts that both approaches would benefit from greater sensitivity towards the unequal context through which strategies emerge and that they serve, in part, to reproduce. Third, the article provides an empirical case study of strategy in a UK Building Society. It attends to how power is exercised in ambiguous and contradictory ways that both supports and thwarts managerial endeavours. Through considering the uncertainty that results from this, the case reflects on the possibilities for resistance. The central argument is that if we explore practice only from management's perspective, then we are in danger of not only reinforcing the status quo but also of being irrelevant to practitioners and wider constituents
