Neutronic calculation and power maps investigation of PWR critical lattice experiments using WIMSD-5B and CITVAP v3.1 codes
The calculation of integral parameters and power distribution is a very important task for fuel assembly design and whole core safety analysis. In this work, we used Monte Carlo (MCNP5) and deterministic lattice cell code WIMSD-5B with the diffusion code CITVAP v3.1 to assess the accuracy of neutronic calculations of three PWR lattice benchmark problems defined by the ANS Ad Hoc Committee on ...

A commercial approach to solar power distribution in India
In India, approximately 5,000 of 79,000 unelectrified villages, either unapproachable from the grid line or subject to uneconomic viability, are awaiting electricity through SPV power as the only suitable technological option. SPV power, which is expensive in capital cost, although affordable in tariff, is on successful trial through a novel scheme that is subsidy-free. Limited scale ...

How Do Relays Function in Industrial Power Distribution Systems?
How Do Relays Function in Industrial Power Distribution Systems? Power distribution systems that manage large currents come with components that protect the system from abnormal conditions, which can damage the unit. One of these components is a relay, which is used to isolate, limit or control electrical loads. Relays, or simple switches that are set off or activated via an electrical ...

Topological model and analysis of the P2P BitTorrent protocol
In this paper, we propose a directed and weighted graph model for describing P2P networks using the BitTorrent protocol. Then, we analyse the topological properties of the model based on the complex networks theory. We find that the node strength follows a power–law distribution and that there exists a positive correlation between flow betweenness and out–strength. We also include ...

Power Injector
Power injector, also known as plug in POE injector, inserts power injector, etc. Power injector provides an alternative to local power supply, multi-port POE power switch and multi-port power distribution board to increase the flexibility of WLAN access point deployment. The power injector usually uses external power supply to provide DC power supply and sends it to the access point (AP) together ...

Performance evaluation of Indian electrical distribution utilities in the post Electricity Act 2003 era
Indian electricity sector constitutes a contrast a highly sophisticated modern generation and transmission system, but a very poor distribution system in several utilities. Despite the realisation of the importance of the distribution sector, the performances of Indian distribution utilities have not been measured empirically so far. The post Electricity Act 2003 (EA 2003) era has witnessed ...

Quick Mapping Evaluator - application for ontology mapping evaluation: a case study on nuclear reactor domain
A comparative study of different string similarity metrics for ontology mapping using Quick Mapping Evaluator (QME) has been carried out. A Java Swing based GUI application, QME, has been developed. This QME is equipped with different algorithms like String Equality, Longest Common Subsequence and Levenshtein Distance for evaluation of the ontology matching at different thresholds in terms of ...

What is HV and LV Power Distribution System?
An HV power distribution system simply means a high voltage distribution system while an LV is a low voltage or tension power distribution system. LV power supply can be around 230 Volts for a single-phase connection and 400 Volts for a three-phase connection. On the other hand, the HV distribution system can even reach 11Kilo-Volts, meaning it is highly used by bulk power purchasers like ...

A novel invariable carrier frequency multi–level inverter PWM for balancing switching transitions and better distribution of harmonic power
The number of switching per modulation cycle at each level in a multi–level inverter depends on the carrier frequency and the duration that the reference waveform dwells within the level. The variable carrier frequency band (VFCB) approach creates as many clusters as the number of carrier frequencies and consequent deterioration of the harmonic spectrum. Therefore, a new pulse width modulation ...

Power-law distribution of acid deposition
The scaling behaviour in acid deposition dynamics of 184 monitoring sites under the National Atmospheric Deposition Program (NADP) is analysed for the 1978–2001 period. The results show that: the distribution of weekly hydrogen deposition (WHD) is consistent with a power law in two different regimes separated by a crossover WHD (CWHD), and both the CWHD and its probability density increase as the ...

PSO-based feedback controller design of DSTATCOM for load compensation with non-stiff sources
Shunt compensating devices like distribution static compensator (DSTATCOM) are extensively used for compensating harmonics/unbalance/voltage sag-swell in a power distribution system. The design and performance of DSTATCOM for load compensation with stiff and non-stiff sources have been well reported in literature. Using linear control strategies like linear quadratic regulator (LQR), feedback ...

Hazards of Transmission and Distribution Lines in Winter
Freezing is an important reason for the breakdown of towers (poles) of power overhead transmission lines and power distribution lines in winter. Strengthen and improve the anti-freezing ability of power transmission and distribution lines, ensure safe, reliable and economical operation, and effectively reduce the accident rate of power transmission and distribution lines. It is related to the ...
