Dynaspede Intergrated Systems Limited

Dynaspede offers a Moment of Inertia measuring equipment for computation of moment of inertia of liquid contained in tanks along different axes.

 

For measurement for roll moment of inertia:
The equipment provides a self-contained platform needed to conduct studies on different liquids, contained in different container shapes in order to determine its roll Moment of
Inertia along its Centre of Gravity or with reference to any axis of rotation displaced from its CG. The equipment has a DSP-based control system for high-speed sampling and computation.
Although designed for measurements on liquids, the instrument is equally suitable for direct measurement of MOI of solid bodies of any geometric complexity, falling within the capabilities of the equipment.

 

While the operating principles are based on well-known concepts of a torsion pendulum, the design of this measuring equipment is proprietary to Dynaspede with many outstanding features in comparison to hitherto known forms of this equipment.

For measurement for pitch /yaw axis moment of inertia and the centre of gravity:
The instrument, in its present form, is designed to provide a self-contained platform needed to conduct studies on liquids filled to required levels and capped within scale models of propeller tanks to determine the location of CG (about hinge point) with and without liquid; computation and display of Lateral M.I. of liquid about an axis passing through its own CG and Damping characteristics.

This equipment is operating on the Principle of Compound Pendulums.

Keeping pace with the latest technologies, Dynaspede offers totally integrated automation control panels based on AC or DC drives. These are either stand-alone or multi-drive controls for various sections of a process plant or machinery. The various sections are controlled either in torque or speed mode with closed looped feedback systems employing different types of sensors such as encoders, load cells, torque transducers, thermocouples and pressure transducers.

Empowered with years of application engineering knowledge base, Dynaspede has mastered specialised programming skills, and developed dedicated control hardware and algorithms to achieve the perfect combination of control scheme for any machine or process to meet the industry's most exacting demands

With a combination of high-end PLC, DAQ and SCADA / Lab view software, we can provide you with full-fledged Management Information Systems.

Modern electrical equipment demands Power Quality, which imposes stringent demands on voltage stability and power quality. The power network has to be free from harmonics and other electrical disturbances.

Multiple Frequency Currents and Voltages existing in the Power System, which are integral multiples of fundamental 50 Hz waveform, are called Harmonics, or “dirty power”. Odd positive and negative sequence harmonic currents, are generated by three-phase full wave, non-linear loads, which are connected to a three-phase, three or four-wire distribution system. Odd positive, negative and zero sequence harmonic currents are generated by single-phase, full-wave non-linear loads which are connected phase to neutral in a three phase, four wire distribution system.

Harmonic Currents produce Harmonic Voltage distortion also depending on system impedance. The major contributors of Dirty power (Harmonics) are:

• Variable speed drives
• Power rectifiers
• UPS, SMPS of computers and the like, LAN/ Servers, printers
• Photo copiers, Facsimiles,
• Electronic ballasts
• Virtually all-low power electronic devices
• Saturated Cored Transformers, inductors and chokes.

Electrical loads generate and absorb reactive power in the process of their work. Since the transmitted Power and load varies considerably from time to time in the course of an hour, the reactive power balance in a grid varies as well. The result can be unacceptable voltage amplitude variations, a voltage depression, or even a voltage collapse. A rapidly operating Static Reactive Compensator (SRC) can continuously provide the reactive power required to control dynamic voltage swings under various system conditions and thereby improve power system transmission and distribution performance. A Dynamic response system such as SRC will provide the necessary amplitude and phase angle support for the voltage waveform. Installing an SRC at one or more suitable points in the network can increase Power transfer capability and reduce losses while maintaining a smooth voltage profile under different network conditions. In addition, an SRC can mitigate active power oscillations through voltage amplitude modulation.

Dynamic Reactive Compensation

The power flow on utility grids consists of both active and reactive power. The difference is due to the fact that the wave of alternating current always leads (capacitive load) or lags (inductive load) the voltage wave. Reactive power (measured in volts-amperes reactive, or VAr) is the product of voltage and out of phase component of alternating current.

Utilities and industries pay close attention to reactive power because it determines how the voltage declines or 'sags' on an electric network. To stabilize voltage conditions, the generated reactive power has to be compensated. To an electric power consumer, optimisation of an existing power system increases productivity, decreases utility charges, and improves equipment reliability.
