“…It is a well-known phenomenon described in [11,12], which consists in the fact that with relative rotor oscillations in antiphase, there occur fluctuations of the unit rotor revolution angles relative to the synchronous speed. Therefore, the mechanical torque of a diesel engine, like the electromagnetic torque of a synchronous generator, is represented in the form of two components of the rotor revolution angle relative to the synchronous speed and synchronizing speed, proportional to the angle deviation.…”

The paper suggests an improved method of active power distribution among the gas-diesel generators operating in parallel; the method involves the control of torque and the angular positions of their rotors. The use of the suggested approach to the solution of the active power distribution task in the presence of instability of drive motor speed provides the increase of autonomous power system operation efficacy and rising the power unit's performance. The authors analyzed the causes of generation of low-frequency fluctuations of generator drive engine speed; in autonomous electric power systems, gas diesel generators are increasingly used as such generator drive engines. It is suggested to use the developed method and structure of the optical device for control of rotation period and the measurement of the generator rotor angle position characterized with high accuracy, as the sensor. The authors developed a schematic diagram of active power distribution among the generators operating in parallel, which uses the cross feedback for gas-powered diesel engine shafts momentum and the generator rotor angle position. They obtained experimental results confirming the efficiency of the suggested active power distribution method and its practical implementation. Keywords-active load sharing, frequency instability, gaspowered diesel engine, optical sensor, rotor angular position I. INTRODUCTIONNE of the most important parameters of diesel autonomous power plants is the cost-effectiveness, which is determined by the ratio of the power generated to the fuel consumption per an operation hour. The fuel consumption reduction will provide the improvement of power efficiency of autonomous power systems (APS). The optimal diesel-generator load is the load proximal to 80% of their rated power [1]. When a dieselgenerator operates at lower loading, the specific fuel consumption increases with the development of carbonization effect caused by accumulation of incomplete combustion products, which produces a negative effect on the engine resource. The generator unit loading above 80% also results in significant performance reduction [1,2].The increase in the diesel fuel price results in the need to convert diesel vehicles to gas. Currently, gas-powered dieselgenerator sets (GDGS) are widely used to provide reliable power supplies at industrial facilities. Gas-powered dieselgenerator sets (GDGS) are increasingly used due to their cost

Permanent Magnet Synchronous Motor (PMSM) has been gradually more used in industrial application as a result of a rapid dynamic response and precise control. This paper proposed a high performance Field Oriented Control (FOC), which is a closed loop control to get better dynamic performance of the PMSM in addition to improve accuracy speed control. Two types of controllers are used; the first controller is the Proportional-Integral (PI) and the second controller is a PIcontroller founded on Fuzzy-PI controller in terms of reducing steady state error, rising time, overshoot and smoother speed response. Space Vector Pulse Width Modulation (SVPWM) method is considered according to harmonics result and losses. A MATLAB/SIMULINK program is arranged for simulating the whole drive systems. The simulation results prove the various dynamic operations.

Permanent magnet speed regulation is an energy-saving technology that uses magnetism coupling to realize the torque transmission of non-mechanical connection and changes the gap of the permanent magnetic coupler to adjust the speed of the load. Experimental research on the air-cooled permanent magnet speed regulation according to the actual operation parameters of 500 kw oxidation fan has been conducted in this paper. Analyses of the problems about the rupture of the load ring at the end of the load on the permanent magnetic speed regulation, large motor vibration, noise and so on appeared during the process of the test have been made and improved measures are proposed.
