Abstract
Development and implementation of new Automatic Generation Control (AGC) algorithms requires testing them on a model that adequately simulates primary energetic, information and control processes. In this article an implementation of a test platform based on HRTSim (Hybrid Real Time Simulator) and SCADA CK-2007 (which is widely used by the System Operator of Russia) is proposed. Testing of AGC algorithms on the test platform based on the same SCADA system that is used in operation allows to exclude errors associated with the transfer of AGC algorithms and settings from the test platform to a real power system. A power system including relay protection, automatic control systems and emergency control automatics can be accurately simulated on HRTSim. Besides the information commonly used by conventional AGC systems HRTSim is able to provide a resemblance of Phasor Measurement Unit (PMU) measurements (information about rotor angles, magnitudes and phase angles of currents and voltages etc.). The additional information significantly expands the number of possible AGC algorithms so the test platform is useful in modern AGC system developing. The obtained test results confirm that the proposed system is applicable for the tasks mentioned above.
Highlights
Automatic Generation Control (AGC) systems must be constantly developed due to changes in market conditions, increasing degree of automation in the energy sector, development of computing systems, increasing number of Phasor Measurement Units (PMU), necessity of improving the reliability of power systems and changes in network configuration.At the moment the AGC system of Russia operates on base of CK-2007 which is the main SCADA system used by the System Operator of the United Power System of Russia
As was already mentioned above, in addition to practical tasks related to the interaction with the unified AGC system of Russia, research tasks can be solved
As an example of a research task, an external program for Operational and informational software complex (OIC) CK-2007 has been developed that partially reproduces the functionality of the AGC system
Summary
AGC systems must be constantly developed due to changes in market conditions, increasing degree of automation in the energy sector, development of computing systems, increasing number of Phasor Measurement Units (PMU), necessity of improving the reliability of power systems and changes in network configuration. At the moment the AGC system of Russia operates on base of CK-2007 which is the main SCADA system used by the System Operator of the United Power System of Russia. Making changes to the settings and adding new algorithms requires testing the AGC system on adequate power system model. One of the complexes that allow real-time closed-loop testing of AGC system in composition with SCADA system is HRTSim, which was developed at the Tomsk Polytechnic University.
