Ups-imitator

Simulates the operation of UPS, calculates and loads current parameter values ​into it via Modbus
Intended for testing the monitoring system

Work scheme

In this work was used mock ups controller

Operating modes

1. Auto
   Work in cycle:

   • q0 — The electrical network is connected, the battery is charged;
   • q1 — The electrical network is turned off, the battery is discharging;
   • q2 — The electrical network is turned off, the battery is discharged;
   • q3 — The electrical network is connected, the battery is charging.

   

2. Manual

   Manually changing parameters via rest api
   Swagger documentation

Getting started

1. Prepare config
   example:

    ups_addr = "127.0.0.1:1502"
    rest_api_bind_addr = ":8080"
    ups_sync_interval = 30 # sec
   
    cycle_change_timeout = 3600 # sec
   
    default_input_ac_voltage    = 220   # V
    max_bat_group_voltage       = 54    # V
    min_bat_group_voltage       = 42    # V
    load_power                  = 1000  # W
    default_bat_capacity        = 50    # Ah
    charge_current_limit        = 20    # A
    low_soc_trigger_alarm       = 0.1   # from 0 to 1, 1: 100%

2. Build

   make

3. Run

   ./bin/ups-imitator

Testing

make test

Results of work in auto mode

1. Launch mock ups controller;
2. Launch ups-imitator (pre-specify the mock-ups address in the config);
3. Launch ups-agent to read data from the UPS.
