Citation X Captain reported generator and bus failures on approach. The Flight Crew requested priority handling and made a precautionary landing at destination airport.

Narrative

We took off from ZZZ1 taking one passenger to ZZZ2. At XA45z/XB45 local we were descending into ZZZ2 and setup for the visual to Runway XXL. We were level at 5000 ft. and ATC gave us a descent to 4000 ft. The airplane was in the clean configuration. I started the descent and not long after my headset got really loud. The noise cancelling function had turned off and at the same time there was an echo over the loudspeaker. Simultaneously; the left Pilot GTC turned off and the master caution illuminated. When I looked at the PFD I saw a yellow X over the AOA; yellow 'Both on ADC 2' message; RA FAIL; and numerous CAS messages. The CAS messages were: TCAS Fail; AOA Probe FAIL R; Slats Fail; DC GEN OFF L; DC EMER BUS L; and Flight Control Fault. On the MFD the throttles were in revisionary mode (yellow REV); the total fuel had yellow dashes; the left fuel tank had yellow dashes; the flaps were yellow; and the left electrical side showed -10 Battery amps; and -10 Gen Volts. I clicked the autopilot off and the auto throttles off. Pilot Not Flying (PNF) notified ATC that we had an issue and would need a vector to the north. I told the PNF I would fly and talk to ATC and asked him to start the checklists.We were given vectors and started the checklists. The first checklist was for the Flight Control Fault. The next checklist was for the DC GEN OFF L. While the PNF completed the checklist I notified ATC that we would need to change our destination from ZZZ2 (5000 ft. runway) to ZZZ (10114 ft. runway). I told the Controller that we wanted the longest runway available; and he said it would be Runway YYL. The next checklist was the 'No Flap Approach and Landing' checklist. ATC asked how long we needed to circle; and I told him roughly 10 minutes; and that we had some issues with failures. I requested priority handling and asked for the trucks to be standing by. I advised that our flaps had failed; and we would need all of the runway. ATC was advised that we had 3 souls onboard and 1.5 hours of fuel. Weather at ZZZ was VFR with wind right down Runway YY. The PNF completed the runway computations for a no flap landing; and we briefed the approach. Our REF speed was 151 and the deck angle would be higher than normal; not much of a flare at all; and no left TR. The PNF was to monitor my speed and AOL along with the ILS glides lope to help back me up. Our computed runway needed for 28000 pounds at landing was 4200 ft. I landed and immediately deployed the speed brakes. I brought the TR to reverse and PNF called the right side had deployed. I left the right side deployed but at idle thrust to prevent asymmetrical thrust. I used brakes to stop and we rolled to the end of the runway and made a left turn to exit. We were followed to the FBO by the fire trucks. Firemen monitored the temperature of the brakes/tires after we parked. About 15-20 minutes later the temperature on the right-side mains was at 1150. The left mains did not get that hot.
