Prototype of Monitoring and Controlling System on Gondola Cage Security Based Android Application

Abstract

Gondola is one of the facilities used in high-rise buildings that are used to access the outside of the building. Gondola has a maximum load limit that is safe to transport it. Gondola is also often damaged in the cage caused by collisions on the side of the building. Until now, the gondola control still uses buttons which also often experience problems. This study aims to provide monitoring of the cage load and provide information about the distance of the cage to surrounding objects. Gondola control through an android application also includes this research in order to provide an alternative if the buttons on the gondola control experience problems. The short-term goal of this research is to carry out an innovation in the gondola field by conducting experiments through prototypes. The medium term goal is to apply the results of this research into a gondola. The results of this study control and monitoring can function properly even though the results produced are not yet accurate due to the imperfect quality of components, materials and assembly.

Distribution Transformer Synchronization Simulation with Two Different Vector Groups using the Matlab Simulink

“…In industrial environments that have large electrical power and loads, parallel transformer systems are often used to simplify maintenance and to increase electrical energy in the future [9]. In these companies, if there is a disturbance or damage to one of the parallelized transformers, it will reduce the capacity of the electric power to be distributed, so that it can reduce production results due to not being able to run production machines optimally, then the alternative is to replace the transformer with how to rent or buy a transformer that has almost the same technical data, as for the obstacles in the field, often the available transformers have a different group vector or transformer clock with the transformer installed so that the handling of blackouts takes longer due to the assumption that they cannot be synchronized, so replacement is needed as soon as possible by synchronizing existing transformers with due regard to other synchronous requirements [10]- [13]. For the PLN environment, a parallel system is carried out to minimize blackouts due to maintenance or additional power capacity to be supplied [14]- [16], for example for substation or transformer maintenance activities, it is required to do blackouts for the safety of workers and the unit itself.…”
