Telecommunication circuits and leased lines have been in use for controlling substations for many years. These circuits have usually been engineered according to set standards however recent studies have shown that the parameters used for engineering the telecommunication circuits have various design flaws that may put these circuits. in jeopardy during a local substation fault. The existing protection scheme for SolarI wind and other relevant power generating farms are such that if they lose communication with the local Utility Transmission Station (UTS)I the UTS automatically trips a local breaker and knocks the generation plant off the grid this could mean thousands of dollars in lost revenue for the generation company hence even a minor flaw in the telecommunication circuits can have a significant impact on the substation control system. This case study reviews the challenges of designing these telecommunication circuits for control and monitoring of substations and also reviews the case study performed by Hydro Quebec on the concept of Zone of Influence. In addition this study also proposes an alternate telecommunication model that when implemented will be able to withstand all the challenges of designing a circuits for the high voltage substation.

Operational Data

Urban traffic can be curbed in various ways, for instance, by introducing paid unguarded parking zones (PUPZ). The operational functionality of this system depends on whether or not the various system features used to document parking cases function properly, including those which enable positioning of vehicles parked in the PUPZ, recognition of plate numbers, event time recording, and the correct anonymisation of persons and other vehicles. The most fundamental problem of this system is its reliability, understood as the conformity of control results with the actual state of matters. This characteristic can be studied empirically, and this article addresses the methodology proposed for such an examination, discussed against a case study. The authors have analysed the statistical dependence of the e-control system’s measurement errors based on operational data. The results of this analysis confirm the rationale behind the deployment of the e-control system under the implementation of the smart city concept in Warsaw.

The Mathematical Model

Abstract By exemplifying the feeder service for the port of Kotka, this study proposed a multi-objective optimization model for feeder network design. Innovative for difference from the single-objective evaluation system, the objective of feeder network design was proposed to include single allocation cost, intra-Europe cargo revenue, equipment balance, sailing cycle, allocation utilization, service route competitiveness, and stability. A three-stage control system was presented, and numerical experiment based on container liner’s real life data was conducted to verify the mathematical model and the control system. The numerical experiment revealed that the three-stage control system is effective and practical, and the research ideas had been applicable with satisfactory effect.
