微机型母线及失灵保护现场适应性及反措问题研究

本文针对我省目前在220kv、110kv系统中广泛应用的微机型母线及失灵保护装置，在产品设计和制造过程中仍存在的不完善，以及在现场运用中存在的问题，提出了更好的解决方案。主要解决几个方面的问题：(1)双母线分段运行时微机母线保护的灵敏度与可靠性的自适应问题；(2)是微机母线保护取自现场的刀辅接点可靠性问题。(3)母差保护和失灵保护复合电压闭锁电压定值应该分开整定的问题。

Research on Resource Development Countermeasures and Environmental Governance of Cruise Tourism Enterprises in China

The development of tourism resources aims to process tourism raw materials into direct-consumption tourism products. The essence of this behavior is innovation. The theory of innovation in economics, management, sociology, oriental management, and related disciplines provided methodology for the development of tourism resources and pointed out the direction. With the development of tourism, the cruise economy has grown and the urban economy has been rapidly developed and improved. However, while cruise tourism brings economic benefits, the discharge of various waste water and exhaust gas from cruise ships of major cruise companies also brings about some environmental pollution problems. Therefore, the environmental protection issue of cruise tourism companies is a sustainable development issue. Persisting in sustainable development strategy, we attach importance to the environmental governance of the cruise tourism industry.
