The utility model provides an efficient energy-saving system for outputting green steam through coupling of shallow geothermal energy and a high-temperature heat pump, and belongs to the technical field of energy systems. The problem that an existing steam supply system cannot generate green steam energy is solved. Comprising a shallow ground source heat pump system and a high-temperature heat pump system which are connected in series, the shallow ground source heat pump system comprises a buried pipe heat exchange system, a ground source side automatic make-up pump, a water collector, a ground source side circulating water pump, a water segregator and a ground source heat pump host, and the buried pipe heat exchange system is connected with the water collector and the water segregator; the high-temperature heat pump system comprises a heat source side circulating water pump, an evaporator, a compressor, an electronic expansion valve, a condenser, a flash evaporator, a high-temperature hot water circulating pump, a preheater and a high-temperature heat pump automatic make-up pump; according to the utility model, renewable geothermal energy and certain electric energy are utilized for assistance, high-temperature steam is output, the production load requirement of the park is met, carbon emission is avoided, carbon sink is increased, and the economic benefit is high.

The invention discloses a multi-standard power supply system and method for a locomotive test, and relates to the technical field of test power supplies, and the structural design of the system is as follows: an input power supply is a three-phase alternating current 10kV power supply; the high-voltage switch K realizes access control and isolation of the system and a public power grid, the connection reactor L realizes energy buffering and inhibits switch ripples in output current, and the soft charging circuit pre-charges the three-stage converter. The three-level converter converts three-phase alternating current 10kV into DC1500 / 750V and outputs the DC1500 / 750V to the direct-current bus, one path of the direct-current bus supplies power to a subway vehicle test line, and the other path of the direct-current bus is inverted into single-phase alternating current 25kV through the output inverter and supplies power to a railway locomotive test line. According to the invention, alternating current test conditions of railway electric traction locomotive vehicles and direct current test conditions of subway vehicles can be satisfied, reliability and quality of power supply are ensured, repeated construction is reduced, and resource waste is avoided.
