  • TURBINE CONTROL AND PROTECTION SYSTEMS

    Turbines are at the heart of the electric generation process and play an active role for converting mechanical energy into electric energy. Turbines can be classified as steam, gas, hydro and wind turbines according to the energy resources they require. Parameters that are controlled in a turbine control system may be adapted based on the type of energy resource. As an example, for the purpose of continuous and quality energy production in thermal power plants, it is necessary to control and monitor different parameters such as water amount and water circulation, control of feed-water, boiler water temperature, amount of fuel, pressure, igniter control system, water cooling system, all the way from burning fuel stage to obtaining steam and turning turbines. Turbines can be controlled with PLCs or dedicated control devices. These systems perform critical closed closed-loop algorithms such as speed and load control. Apart from general SCADA interface for controlling and monitoring, alarm and reporting functions can be provided with a local and dedicated interface. Data obtained from the site can be transferred into SCADA system.

    Benefits
  • Low lifespan cost
  • Optimized operation
  • Excellent reliability
  • Increased turbine lifespan via sensitive controls
  • Short commissioning time n Decreases in fault costs and repair times
  • Fully automated operation eliminating operator errors
  • Quick access to information
  • For Turbine Control Systems, we use ABB AC800M and AC870P solutions and Woodward turbine control solutions. Turbine protection systems and valve positioning products are additional components supplementing the system. Speed, the most critical parameter for rotating parts, is continuously monitored. Protection systems are connected to other field devices such as speed measurement devices and servo valves in turbines. These provide over speed protection and valve positioning controls independent from main control. Turbines are protected and their lifespan is extended by monitoring many critical parameters such as speed, oil pressure, temperature, etc. As a result, a quicker, more flexible, functionally enriched turbine control system is obtained.

    NETWORK CONNECTION AND POWER QUALITY

    The reliability and quality of energy being produced is indeed very important. Simply put, quality of energy is protection of rated value of amplitude and frequency of voltage and sinusoidal character of the wave in any point on the network. Since electric power needs to be continuous and can not be stored on the consumer side, it is not possible to provide any assurance of quality and inspection before use. Therefore, the energy generated should be reliable and in high quality. Unfortunately, power generated in high quality from the generators cannot be transmitted to the consumer keeping its initial quality. After generation phase, connection of electric power to the grid also should also be performed in a way to keep maximum quality.

    Primary frequency control

    Primary frequency control (PFK) service enables bringing system frequency to a new balance point by means of automatically increasing or decreasing active power output of the unit via speed governor, in reaction to decrease or increase in system frequency. In other words, when system frequency decreases below 50 Hz, active power production is increased via speed governor located in the turbines and frequency is stopped at a value below 50 Hz. (e.g. 49.70 Hz). Bringing the frequency stopped at this value to its former value (50 Hz) will be possible with secondary frequency control. Power plants have redundancy for such purposes.purpose of showing function of primary frequency control. During primary frequency control performance tests, the following values are measured and recorded along with other values deemed necessary by the testing team:

  • Active Power Output (MW)
  • Network Frequency
  • Simulated Frequency
  • Valve Positions
  • Steam Pressure (TEPP)
  • Steam Temperature (TEPP)





  • During primary frequency control performance tests, sampling rate of measurement made for each value should be 10 data per seconds.Primary frequency control performance tests consist of three stages:

  • Primary Frequency Control Reserve Test
  • Primary Frequency Control Sensitivity Test
  • Primary Frequency Control 24 Hours Verification Test
  • MCC PANEL SOLUTIONS

    MCC panels are panel systems where engine main feeding units and control devices are located. Control devices such as PLC and DCS and other devices required for SCADA and communications infrastructure are found in control section of the MCC panel. Panels are important components of the system and are supplementary in projects we implement. For all systems that we install, Kontrolmatik can produce type-tested distribution panels including form 4-B, MCC Panels (Motor Control Panels) and Motor Driver Panels up to 400 KW within our own capacities. In accordance with IEC 60439-1 standard, we separate functional sections from each other within the panels with form applied LV Distribution and MCC panels, in order to increase the safety of personnel and facilities. For custom applications, we can produce panel applications with IP66 protection class as well as UL50 certified panel applications in accordance with American standards. We use RAL7035 and RAL7032 colors as standard. We use custom-designed bus systems for power distribution systems and especially MCC panels




    Switchyards Switchyards enable transmission of energy generated with quality electric infrastructure and automation, in an uninterrupted and secure way with minimum losses. Monitoring and control of the status of LV switches and power supplies, all MV circuit-breakers and disconnectors in main and sub-stations of distribution systems, monitoring the whole switchyard from a single central point controlling via SCADA are essential for security.
