In the framework of the investment "Development Programme and technical retooling of JSC" Mosenergo "," KER-Engineering "took an active part in the reconstruction of electrical equipment at TPS-17 and TPS-23 in Moscow.
So, power unit No. 4 at TPS-17 was reconstructed in the following way:
• obsolete turbine generator T-100-2 with electric machine excitation was replaced for system with a modern-110-2MUZ TSFP turbogenerator 110 MW with static thyristor excitation system (JSC "Power Machines");
• the protection of unit generator - transformer-based microelectronic REG-216 (ABB) was installed and put into operation;
• two 20 kV gas-insulated circuit breaker transformer TSN-2 were mounted;
• the control panels and protections of the main control board were reconstructed.
Similar work was performed at TPS-23 on the power unit st. №2. In addition, there was 220 kV outdoor switchgear reconstruction with replacement of oil circuit breakers 220 kV Y-220-2000 for gas-insulated WBE-220-2000-40.
