LITERATURE SURVEY: TITLE 1: Quality Improvement of ESP in Mechanical Engineering AUTHOR: Alina- Andreea Dragoescu YEAR: 2010 DESCRIPTION: The latest political positioning of Serbia has caused many changes in the society with the most dramatic economic shift on the market. The market requires young educated employees with special additional “soft skills”. This has resulted in the need to change the Serbian educational system with the Bologna process implemented. Therefore, the syllabus of ESP in Mechanical Engineering must be adjusted to the demands as regards needs analysis so that it can meet the requirements of the rapidly growing market. This paper offers an outline of ESP syllabus which can be regularly updated with respect to technological and other changes on the market TITLE 2: Automatic control and management of electrostatic precipitator AUTHOR: N.V.P.R. Durga Prasad, T. Lakshminarayana YEAR: 2002 DESCRIPTION: The efficient operation of electrostatic precipitator (ESP) in practice depends upon many variables, such as the charging method, particle size, gas flow, temperature, dust resistivity, etc., with the air pollution control requirements becoming increasingly stringent, it is essential to closely monitor and accurately control the key parameters of ESP control system. The efficient functioning of ESP normally
means minimizing the power consumption and maximizing dust collection. Several control strategies can be adopted to meet this broad requirement. In this paper, a distributed control technique of ESP which uses the actual dust emission and boiler load as feedback inputs is explained. The electrostatic precipitator management system (EPMS), which is a system designed by M/S BHEL to meet the above control strategies using the distributed architecture to achieve efficient ESP operation is also described. TITLE 3: The Analysis and Design of Steel Plant Electrostatic Precipitator Control System based on IFIX AUTHOR: Kaixing Wu, Yuqing Zheng YEAR: 2009 DESCRIPTION: Electrostatic precipitators (ESP) are the most widely used devices which are capable of controlling particle emission effectively from steel plants and other process industries. The performance of an electrostatic precipitator is significantly affected by its complex running parameters. Once they are set inappropriately, the failure rate will be increasing. It is, however, difficult to find the fault’s causation and position, which reduces collection efficiency and drops the level of management automation. More importantly, that makes gas emission over standard, the environment polluted. Aim at the above problems, this paper proposes a kind of ESP control system based on iFix configuration software. The system brings iFix’s automatic function of data acquisition and data management into full play, and improves equipment utilization and management degree of automation as well. This system includes real-time monitoring picture, alarm processing, report processing and so on. The implement of the system achieves the
goal of improving collection efficiency, pro-environment and energy conservation, enhancement of security, saving manpower and material resources and convenient for management and maintenance, so it’s very worthy of expanding. TITLE 4: THE OPTIMIZING CONTROL OF THE OPERATION VOLTAGE FOR ELECTROSTATIC PRECIPITATOR BASED ON INTELLECTIVE METHOD AUTHOR: DA-ZHONG LI , LI TIAN , SHU-PING LIU YEAR: 2006 DESCRIPTION: For the problems of dust discharging concentration and power consumption in power plants, a new optimizing control method on the whole was presented to improve the performance of the electrostatic precipitator. The corona power model was identified by least-squares method and dust concentration of the outlet was represented by the neural network model. Based on this, the operation voltage optimization was realized by GA. Simulation results show that this control method can not only ensure the collection efficiency but also save energy. TITLE 5: Optimization Design of Multi-level Combination Electrostatic Precipitator Electric Field Voltage Control AUTHOR: Li Qing, Liu Lihua, Liu Zhiqiang YEAR: 2010 DESCRIPTION: For realizing automatic voltage control and automatic protection, the traditional mechanical potentiometer was replaced by an automatic unit with hardcore device:
microcomputer-single chip and digital programmable potentiometer (DPP), and the power voltage of the electrostatic precipitator (ESP) were adjusted exactly by the auto unit. The automatic control process of the ESP’s work voltage was described in detail by a three combined electric field model with 150mm between discharging electrode and collecting plate, by monitoring parameters of the ESP entrance particle size and the exit dust concentration were depended on. The corresponding flow chart was given out. TITLE 6: High Voltage Power Supply and Control Technologies for Electrostatic Precipitators in Biomass Applications AUTHOR: Norbert Grass, Thomas Fischer YEAR: 2014 DESCRIPTION: This paper will show the specific requirements of high voltage power supplies and their control technology related to small size electrostatic precipitators as they will be used in applications of biomass fired furnaces in the near future. Unlike large ESPs, which are installed in heavy industrial plants (e.g. coal fired power stations or steelworks), the small electrostatic precipitators will mainly be used on private properties or small businesses and hence, be operated by people even without any technical background. Therefore, additional requirements need to be considered in the design of the power supply and the control of such a system, that full automatic operation with continuous optimization can be achieved without operator interaction or maintenance. Available power electronic topologies e.g. soft switched, resonant, or pulsed mode will be evaluated and classified by a strength and weakness analysis. Additionally, the collection efficiency is strongly depending on the control performance of the system. Critical operating situations
like heat up phases with fairly unstable combustion processes need exact adaption of voltage and current dynamics to achieve the required precipitator performance. Unlike in large electrostatic precipitator plants, flashovers must be merely avoided due to the noise and EMI, which is not acceptable in domestic environments. Fuzzy Logic was tested for the control system to process current and voltage setpoints for the power electronic internal control system. Finally, an example ESP system setup in laboratory state and measured data will show some results to be discussed. TITLE 7: Sliding Mode Traction Control of an Electric Vehicle with Four Separate Wheel Drives AUTHOR: Mahdi Jalili-Kharaajoo and Farhad Besharati YEAR: 2005 DESCRIPTION: This paper, presents a traction control algorithm for an electric vehicle (EV) with four separate wheel drives. This algorithm is necessary to improve the handling and stability of EV during cornering or under slippery road condition. It distributes the traction power among four drives and espccially an independent torque reference on each wheel.
