Simulation Results of DTC by ANN on FPGA
In this work, a neural network using simple inputs such as outputs of hysteresis controllers was studied. Several parametric studies (selection of network type, selection of inputs, selection of outputs.
The use of the high-level design tool 'System Generator' is very beneficial to check the behavior of the algorithm in Simulink. The simulations for the sigmoid function as well as the neural network reveal that the results in Xilinx gave the same performance as the sigmoid function obtained in Simulink as well as the neural network study.

IMPROVED ANT COLONY SEARCH ALGORITHM FOR SOLVING OPTIMAL REACTIVE POWER OPTIMIZATION PROBLEM

- Algorithmic steps
The purpose of the reactive power optimization problem is to minimize the active power loss in the transmission network and to improve the system's voltage profile. The number of cities or the size of the candidate list is also limited to a quarter of the cities n. It is clear that a small value of the heuristic parameter can result in poor performance in the early phase of learning.
Nevertheless, a small value of the heuristic parameter can have good performance when the search process lasts long enough.
Create an Automated Query Generation by Using Parse Tree Query Language as a Solution for Incremental Information Extraction
- Information Extraction
- Basic Generality Techniques
- Link Grammar
- System Approach
- System Architecture
- Parse Tree Database
- Extraction Phase
- Tree pattern: describes the hierarchical structure and the horizontal order between the nodes of the parse
- Link condition: describes the linking requirements between nodes
- Proximity condition: is to find words that are within a specified number of words
- Return expression: defines what to return. We start with the basic element of PTQL queries called node expressions
- Query Evaluation
- Query Generation
The parser's output, called conjunctions, shows the dependencies between pairs of words in the sentence. The initial stage word processor is responsible for processing the corpus and storing the processed information in the parse tree database (PTDB). The intermediate output of the processing modules is stored in a relational database known as the parse tree database.
The generated syntactic trees for parsing and marking the semantic entity of the processed text are stored in the Parsing Tree Database (PTDB).
The first query generation approach takes advantage of manually annotated data to generate PTQL queries for extracting protein-protein interactions. We illustrate our approach with an application of protein-protein interaction inference using a set of syntactic patterns that are expressed in PTQL queries. From this labeled data, the pattern generator identifies relevant phrases that refer to interactions to generate patterns.
PTQL queries are then formed by the query generator to perform extraction from the parse tree database.

Dynamic Performance of HVDC Link based 3-level VSC Supplying a Passive Load
Independent control of active and reactive power (allowing converters to provide damping, frequency and voltage support in AC networks without compromising system performance). This allows the use of inexpensive cables and transformers with lower insulation requirements, as they are not required to withstand high voltage stresses during power return. The vector control method is studied using 3-level VSC connected to an active AC system at the first end and passive load at the second end of the HVDC link.
This simulation shows the performance of the controller in the operating range against some step changes in the load and shows the regulation of active and reactive power.
VSC-HVDC TRANSMISSION MODEL
The active power and reactive power exchanged by the VSC-HVDC and AC system can be instantly adjusted by changing the magnitude and angle of the VSC-HVDC output AC voltage. The VSC can easily exchange active and reactive power with an AC network as well as a synchronous machine. But the range of active power and reactive power that can be adjusted in VSC-HVDC is subject to speed power limit and time operating conditions.
The control power of the active power and that of the reactive power influence each other dynamically.
Phase locked loop Phase locked loop
The active power or DC voltage is controlled by the control of δ and the reactive power is controlled by the control of the modulation index (m). Accordingly, it is possible to control the active power (or DC voltage or DC current) and reactive power (or AC bus voltage) by controlling the current components ivd and ivq respectively. The active and reactive current and voltage loop contains the outer loop controllers that calculate the reference value of the converter current vector (I*dq) that is the input to the inner current loop .
Equations of state representing the dynamics of VSC currents are used (an approximation is made by neglecting AC filters).
MODEL PERFORMANCE ANALYSIS
Case 2 Case 2
During the station 1 side fault, the transmitted power can be kept constant except for a small fluctuation during the fault. The transmitted power flow is reduced to a low value during the fault and recovers after the fault. The DC voltage, which can be controlled to 1.0 pu during the fault, has some oscillations at the beginning of the fault and during the recovery of the fault.
It can also be achieved that during a single-phase fault, the transmitted power can be kept constant except for a small oscillation during the fault.
