Model and Simulation of a Stand Alone Power System Comprising a Diesel Engine Driven Synchronous Generator and a Power Conditioner

Abstract

A model of a stand alone power supply comprising a diesel engine driven synchronous generator, a power conditioner, a bank of batteries, and an adjustable dump load is presented. The response of the power system to two different load profiles is included.

Hybrid wind-diesel powered system DC link stability analysis taking into account load disturbances

“…The main voltage regulation loop generates diesel engine speed control reference [6] [7].permanently, with wind speed dependency, the maximum power point tracking system injects much distorted current inside the DC bus.…”

Modeling and simulation of selected distributed generation sources and their assessment

“…The speed governors have usually second-order or first-order transfer function for a combustion turbine or a diesel engine [6,8,10,13,14,17,18]. To achieve the models of a diesel engine and a combustion turbine, the assumption that the systems have reached a steady state is considered.…”

“…It is convenient to apply Park's transformation with a rotor fixed reference frame. From these two equations (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18) and (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19), the three-phase stator currents and flux linkages can be found. Next, both equations (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18) and (3)…”

“…On the other hand, the rotor flux linkages and voltages could be related by equation (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21). Furthermore, the currents also are decided from flux linkages by using equations (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22).…”

“…The Park's transformation matrix is given as follows (3-15) where Next, applying Park's transformation, Other parameters, such as inductance, flux linkage, resistance, and currents can also be applied. The stator equation (3-13) and equation (3-14) become (3-16) where while the flux linkage and the current's equations become (3-17) where where Next, it is convenient to express the voltage and flux linkage equations in terms of reactance rather than inductance, so all equations are divided by a base frequency,We have below the detailed equation,(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18) with rotor fixed reference frame. In the flux linkage equations, the negative sign of stator currents appear because the direction of the currents is defined as a generator action in the synchronous machine.…”
