The Old and the New: Designs to Enhance Cesano Maderno Old Town through a Regenerative Structure

The relationship between the old and the new is a specific theme of architecture that bears witness not so much to the original appearance of the old but to its enduring meaning in historic Italian and European cities.The complex palimpsest of signs,memories,and overwriting that time has layered on built forms opens questions of meaning that can be untangled only in the relationship between history,site and design.The investigation of structural characters of places and their relationships with cultural assets and heritage provides a layered set of readings,which is itself the forerun of an urban landscape design action.Beyond preserving the integrity of the material traces,there can only be the new.The test bench is therefore the project as a cognitive act around which to build‘case by case’the strategies for recovering urban identity.The series of projects for Cesano Maderno old town,north of Milan,exemplifies a design-led approach to the built heritage and historic urban landscape in which reading tools,conservation and design are shown in their mutual relationship.In this dialectic between the old and the new,the design is part of the architecture of time where the new,working through light reversible overwriting and measured grafting,becomes a further layer in the historical palimpsest and the authentic form of its enhancement and reuse.Integrating project strategies-from pure conservation to new architectural grafting,from reuse to overwriting-the sequence of designs give shape to a‘regenerative structure’that enhances as a system and for public use a set of introverted Baroque buildings and spaces along a historical promenade,re-centring the city around its brownfield core.

Substation area joint defensive protection strategy based on distributed cooperative all-in-one device

Integration of primary and secondary devices are impelled by the development of smart grid. Based on the ideology of primary and secondary device integration, an all-in-one device and its concept, configuration and function are proposed. Then, an all-in-one device framework of distributed substation area protection is proposed. Point-topoint model and virtual local area network(VLAN) based network-to-network model are adopted in this framework.The dual redundancy on hardware and software level is realized by modularization and protection information mirroring storage/overwriting. Considering the fact that the sampling, logic judgment and information sharing processes of protection may fail in atrocious conditions, a distributed cooperative all-in-one device cluster based substation area joint defensive protection strategy is proposed. The adaptability of sectional component failure in secondary system is strengthened by reusing module function, setting value mirroring storage and dynamic load balancing computing ability to constitute strong intelligent outdoor secondary device integrated network. Finally, the simulation examples based on EPOCHS which consider various system failure conditions are presented to verify the validity and rationality of the proposed architecture and strategy.
