Preamb

2、le. This military standard is approved for use by the Department of the Navy and is available for use by all Departments and Agencies of the Department of Defense. 2. Purpose. This section defines the standard interface requirements for and the constraints on the design of shipboard user equipment t

3、hat will utilize shipboard high voltage (industry: medium voltage) alternating current (AC) electric power. 3. Nature of the interface. In any system involving power source, distribution network, and load (user equipment), the characteristics at the system and user equipment interface are mutually d

4、ependent on the design and operation of both. In order for the electric power system to perform within the established tolerances, it is necessary to place constraints on the power source, the distribution system and the user equipment. This interface standard defines the electric power system chara

5、cteristics. User equipment constraints are also established. 4. Structure. The technical content first delineates the characteristics of the shipboard electric power system at the interface in terms of voltage, frequency, continuity, and voltage waveform. Constraints on user equipment design and ins

6、tallation, which are necessary to achieve shipboard compatibility with and to assure these characteristics, are then established. Finally, test requirements are specified to verify conformance of AC user equipment to this standard. 5. Invoking the standard. The Principal Development Activity (PDA) w

7、ill consider the mission requirement of the user equipment being developed or acquisitioned. The PDA will then select those conditions under which the user equipment is to operate and those conditions, which the user equipment will withstand without failure, but not necessarily, operate normally. Th

8、e PDA will also specify those tests commensurate with the equipments mission, which will ensure the user equipments satisfactory operation, the user equipments compatibility with the shipboard electric power system and other equipment, and the equipments survival. 6. Numerical quantities. Numerical

9、quantities are expressed in metric (SI) units. 7. Contact information.

33、act. DEPARTMENT OF DEFENSE STANDARDS MIL-STD-1399 - Interface Standard for Shipboard Systems (Copies of this document are available online at http:/assist.daps.dla.mil/quicksearch/ or http:/assist.daps.dla.mil or from the Standardization Document Order Desk, 700 Robbins Avenue, Building 4D, Philadel

34、phia, PA 19111-5094.) 2.3 Order of precedence. In the event of a conflict between the text of this document and the references cited herein, the text of this document takes precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been

35、obtained. 3. DEFINITIONS 3.1 Electric power system. The electric power system is the electric power generation and distribution system (excluding electric propulsion systems) including generation, cables, switchboards, switches, protective devices, converters, transformers, and regulators up to the

36、user equipment interface. 3.1.1 Electrical interface. The interface is the boundary between the electric power system and the user equipment where the electric power system characteristics and the user equipment compatibility requirements apply. 3.2 Electric power system ground. Ground is a plane or

37、 surface used by the electric power system as a common reference to establish zero potential. Usually, this surface is the metallic hull of the ship. On a nonmetallic hull ship, a special ground system is installed for this purpose. 1 Provided by IHSNot for ResaleNo reproduction or networking permit

38、ted without license from IHS-,-,-MIL-STD-1399-680 3.2.1 Ungrounded electric power system. An ungrounded electric power system is a system that is intentionally not connected to the metal structure or the grounding system of the ship, except for test purposes. An ungrounded electric power system can

39、continue to perform normally if one line conductor becomes solidly grounded. However, an ungrounded system may be subject to over-voltages greater than five times nominal voltage as a result of an inductive arcing ground between one line and ground. 3.2.2 High-resistance grounded electric power syst

40、em. A high-resistance grounded electric power system is a system that employs an intentional high resistance between the electric system neutral and ground. High-resistance grounding provides the same advantages of ungrounded systems (i.e., the system can continue to perform normally with one line g

41、rounded) yet limits the severe transitory over-voltages associated with ungrounded systems. 3.2.3 Solidly-grounded electric power system. A solidly-grounded electric power system is a system in which at least one conductor or point (usually the neutral point of the transformer or generator winding)

42、is intentionally and effectively connected to system ground. A single ground fault from one line to ground will produce high fault current that should cause selective tripping of protective circuit breakers interrupting power service continuity. 3.3 Frequency. Units are Hertz (Hz). 3.3.1 Nominal fre

43、quency. Nominal frequency (fnominal) is the designated frequency in Hz. 3.3.2 Frequency tolerance. Frequency tolerance is the maximum permitted departure from nominal frequency during normal operation, excluding transients and modulation. This includes variations such as those caused by load changes

44、, environment (temperature, humidity, vibration, inclination), and drift. Tolerances are expressed in percentage of nominal frequency. 2 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-STD-1399-680 3.3.3 Frequency modulation. Frequency modulation

45、 is the permitted periodic variation in frequency during normal operation, calculated by Equation 1 and shown in Figure 1. For purposes of definition, the periodicity of frequency modulation should be considered as not exceeding 10 seconds. 100f2ffnominalminimummaximumFrequency modulation (percent)

46、=EQUATION 1 FIGURE 1. Frequency modulation. 3.3.4 Frequency transients. A frequency transient is a sudden change in frequency that goes outside the frequency tolerance limits and returns to and remains within these limits within a specified recovery time (longer than 1 msec) after the initiation of

47、the disturbance. 3.3.4.1 Frequency transient tolerance. Frequency transient tolerance is the maximum permitted departure from nominal user frequency during transient conditions. The frequency transient tolerance is in addition to the frequency tolerance limits. 3.3.4.2 Frequency transient recovery t

48、ime. Frequency transient recovery time is the time elapsed from the instant when the frequency first goes outside the frequency tolerance limits until the instant when the frequency recovers and remains within the frequency tolerance limits. 3.4 Voltage. Units are Volts (V). Unless otherwise specifi

49、ed, voltages in this standard are root- mean-square (rms) values. Tolerances are expressed in percent of the nominal user voltage. 3.4.1 Navy high voltage. For Navy applications, high voltage is considered to be a value above 1000 Vrms. 3.4.2 Nominal user voltage. Nominal user voltage (Vnominal) is the designated voltage at the interface. 3 Provid
