In this paper, the root cause of excessive zero-sequence currents observed when energizing parallel autotransformers in a power system is investigated. The studied system is a large international airport in Canada, where its power is supplied by both utility and local distributed generation (DG) feeding the load through two parallel autotransformers. Recent field monitoring data indicated that when the utility, local generators and the first autotransformer were already in operation, there were rich 3rd and 9th order harmonic currents, which caused the over-current ground relay (51G) to trip, during the second autotransformer energizing through its high voltage side while its low voltage side had already been electrically connected to the system. Through this research, the root cause of the problem is determined to be saturation of the two autotransformers. It is found that this is a special phenomenon that only occurs to parallel autotransformers. The PSCAD/EMTDC simulation is conducted for the system, and the simulation model is benchmarked using field measurement data. Two methods are developed in this paper to calculate the maximum RMS zero-sequence current flowing through the two autotransformers: 1) an analytical based simplified equivalent circuit method, and 2) a curve fitting based mathematical equation method. The solutions to prevent mis-operation of the ground relay are proposed and their effectiveness are validated by simulation, and one method has been currently implemented in the field.

The designer of electrical power systems needs rules of thumb to maintain a full understanding of the circuits sizing and of the results obtained adopting available software programs. At this aim, it appears useful to consider characteristic current densities for the conductors in a tentative of a new approach. Steady current densities support the criteria of sizing the circuits for their continuous operation in the time and for their configuration in the load “space” of the system. Transient current densities characterize the cables withstand behavior. The paper identifies withstand electrical charge densities for overcurrents in relation to assigned intervals of overtemperature. For each assumed transient time, the current densities in the conductors are admissible until they accumulate a charge density not greater than the withstand value.

This paper presents a practical view of how to implement a Dual Modular Redundancy (DMR) scheme in a CPU-FPGA (Central Processing Unit — Field-Programmable Gate Array) heterogeneous platform-based monitoring system, which is also described. FPGAs in a monitoring system can be valuable resources when it is important to either have a reprogrammable system or fast response/acquisition rates when processing large volumes of data. On the other side, CPUs are affordable options for most other processing tasks. A heterogeneous platform is proposed and aims to achieve a reliable, however cost-effective solution. After this, the paper will focus on matters such as synchronization between units, data redundancy and self-monitoring schemes. The implemented design was thoroughly tested, showing effectiveness in terms of redundancy with improved reliability.

For the street light systems the worldwide trend of electrical standards encourages the adoption of Class II equipment such as for the light fixtures, the cabling systems and all the other components. In installations of a largest number of light poles, a safety degradation could be possible and so dangerous electrical potentials may appear on the steel poles and expose folks to shock hazards. To decrease the risk to an enhanced level, different solutions are available. In this paper, the authors deal with a combined action of two safety measures. In particular, these measures are the insulation of the steel poles with an adequate varnish against shock hazards in faulted conditions and the protection of the supplying circuits by residual current breakers to avoid the persistence of ground faults and providing their automatic reset to guarantee the continuity of the service against transitory faults.

A hotel switchboard located in an attached below-grade garage was corroded at its base from water entering through the building wall during extended, high-volume rainfall events. The owner requested replacement of the 35-year-old switchboard to correct several issues, even though several efforts to stop water ingress were not successful. Elevation of the replacement switchboard to guard from contact with rainwater ingress was at first thought infeasible due to low deck-to-deck height in the parking garage. An alternate construction switchboard of shorter height was specified to permit elevation of a replacement switchboard at the original location. An office building interior was thoroughly renovated, with emphasis on flooding resiliency for ground-floor elements including a service switchboard. Sandbags at exterior doors and other evidence of occasional minor flooding of the ground floor emphasized the need for design measures to protect equipment. The electrical room floor-to-ceiling height was only 8′0″, leaving little room for device elevation beyond a standard concrete housekeeping pad. An alternate construction switchboard of shorter height was specified to permit an 18″ elevation in the original location. Overhead working space was retained for use in routing feeder conduits.

Adequate protection scheme is an important defense mechanism for traction power supply system (TPSS), and the reliability of its operation could affect the normal operation of the system. Therefore, in order to maintain the system in safe operation, it is of great importance to quantify the influence of protection scheme on traction power supply system. This paper presents a risk assessment method for traction power supply system considering the reliability of system protection. A risk probability model for system protection is established. Based on Markovian state-space method, the reliability of the protection system is evaluated; the misoperations of the protection system and their possible consequences are analyzed by FMEA method. Three types of economic loss indices are defined to establish the quantitative risk consequence model; the risk of traction power supply system is thereby quantified by integrating risk probability and risk consequence. Practical traction power supply system is taken as an example to prove the effectiveness of the proposed method. The evaluation results can help formulate corresponding measures, and provide guidance for maintenance strategies, thus reducing system risk.

Majority of the loads involved in the operation of steel industries are of non-linear nature. An induction furnace is one typical example of a non-linear load, the growth of which has been a boon to the steel industry. Harmonics convoying with the operation of an induction furnace under fluctuating load situations result in vast power losses and have negative affect on neighboring loads. The aim of the present work is harmonic mitigation using a Unified Power Quality Conditioner (UPQC) of an induction furnace in a steel industry. The experimental readings of the induction furnace are obtained using power quality analyzer. A Simulink model of the induction furnace is designed whose performance matches the real-time data measured from a steel plant induction furnace under operation. The solution methodology proposed by UPQC shows significant improvement in the Total harmonic distortion (THD) content of an induction furnace. The proposed results are also compared with that described in the literature.

Downed distribution conductors in overhead distribution systems, may not be a concern for equipment, but greatly challenge the safety of persons, as well as the integrity of properties. Upstream overcurrent protective devices may not be able to detect the magnitudes of fault currents resulting from these high-impedance faults. Even though protective devices capable to detect such faults have been available on the market, not all the utilities have equipped their stations with these products, likely due to the costs. In this paper, the authors formalize the problem, and propose a possible cost-effective solution for the low-voltage over-head lines with neutral wire. Such solution includes a metal hook underneath the line conductors, supported by the pole, and connected to the neutral wire. This arrangement would cause a line-to-neutral short circuit, positively activating existing over-current devices, which can therefore disconnect the supply. Costs and possible safety issues for workers related to the installation of the device to existing overhead lines are herein also delineated.

Nowadays, the emerging smart grid technology opens up the possibility of two-way communication between customers and energy utilities. Demand response (DR) management offers the promise of saving money for commercial customers and households while helps utilities operate more efficiently. In this paper, an incentive-based DR optimization (IDRO) model is proposed to efficiently schedule household appliances for minimum usage during peak hours. Proposed method is a multi-objective optimization technique combined with Regression Analysis (RA) which is flexible and scalable. In exchange for a discount on electricity prices while minimizing the customer's welfare, the proposed IDRO algorithm coordinates all the monitored and enrolled household appliances for a better use of electricity energy. It is a cost-effective method where a data acquisition device with only one single minimal set of voltage and current sensors is required. Proposed method is tested and verified using 300 case studies (household). Data analysis for a period of one year shows up to %15 power factor improvement, up to %15 cost saving and 5 Kw/h usage reduction during peak hours for individual households.
