Description

[Background technology]

[0001] Generally, electrical power is required to control most functions within commercial and industrial plants and facilities. Additionally, these plants and facilities have critical safety functions that must be maintained to avoid safety degradation or destruction in the event of a power loss. For example, during a postulated accident scenario, a nuclear power plant requires certain systems to continuously maintain electrical power in order to safely shut down the plant and avoid the possibility of core damage. As another example, an industrial chemical plant must maintain control of a potentially dangerous chemical process to avoid explosions and / or chemical leaks. Therefore, many commercial and industrial plants and facilities require backup generators to provide emergency power to the majority of the plant's / facility's equipment in the event of a loss of normal electrical power. However, for many of these plants / facilities, emergency backup power is also required for various critical smaller electrical loads operating at a range of AC and DC voltages and currents to control, operate, and monitor the most critical equipment in order to facilitate safe shutdown and avoid major accidents and destruction. During these power loss events, time is of the essence, and it is essential to restore power to these critical smaller electrical loads as quickly and easily as possible in order to mitigate the event and minimize any damage caused by the power loss.

[0002] For example, during severe accident scenarios and natural disaster events, nuclear power plants have specific time requirements for restoring power to critical equipment (e.g., equipment that provides critical cooling functions to prevent damage or worsening of the event). During severe accident scenarios, if critical equipment loses off-site power and stationary backup generators also fail, nuclear power plants may have a very short time frame, such as within a few hours, before critical damage to the facility occurs. This scenario was exemplified by the 2011 Fukushima Daiichi nuclear power plant earthquake and the resulting nuclear accident. Therefore, there is an urgent need to ensure that nuclear power plants do not go without primary or backup emergency power to their critical safety equipment for a certain number of hours.

[0003] Nuclear power plants are designed with emergency backup power systems that utilize one or more large stationary generators; however, these facilities are complex and difficult to maintain, have limited fuel supplies for prolonged events, and the large stationary backup generating equipment can be affected during natural disasters or prevented from operating by a prolonged loss of the power grid. To address this issue, the U.S. nuclear industry and the U.S. Nuclear Regulatory Commission implemented the "Diverse and Flexible Mitigation Capability ("FLEX") strategy to ensure that nuclear power plants receive power beyond their primary and stationary emergency power systems in the event of a prolonged power loss event. Generally, the FLEX strategy provides for a third form of emergency power through large portable machinery and generators that nuclear power plants can utilize in the event of a prolonged power loss. Additional FLEX equipment is distributed at strategic locations throughout the United States to serve as many nuclear power plants as possible, while simultaneously ensuring that a natural disaster does not destroy more than one FLEX stockpile location. However, the FLEX strategy can be very expensive to maintain, somewhat complicated to implement during a severe event, and may suffer significant delays in activating FLEX equipment to provide power to nuclear facilities during very large natural disaster or terrorist-type events that affect regional or national power grids. Furthermore, FLEX equipment is designed to provide power to an entire nuclear power plant (e.g., just like a large standby generator) and not target only the critical number of pieces of equipment that require power to maintain the safety of the nuclear power plant. For example, a nuclear power plant may only need to provide power to three (3) pieces of equipment and / or components to maintain the safety of the reactor core, while the remainder of the nuclear power plant can remain safe without power. Summary of the Invention [Problem to be solved by the invention]

[0004] There is a long-standing need within the nuclear power industry to be able to provide emergency power response to the most critical equipment loads in a much faster and more efficient manner. Portable power devices necessary to restore power (both AC and DC power) to critical smaller electrical loads regardless of the status of the industrial plant / facility's main power source or stationary backup power or distribution system must be capable of being safely and securely attached to the power distribution system. A poorly connected portable power device may result in arcing, inconsistent power transfer, and / or reduced power transfer. Power provided to the distribution system must be interrupted and / or prevented from backfeeding to the portable power device. [Means for solving the problem]

[0005] It is to be understood that both the following general description and the following detailed description are exemplary and explanatory only and not limiting. What is provided are methods, systems, and apparatus for generating power, transferring power, and / or protecting various critical meter and control circuits and power circuits by enabling measurement and / or analysis of various critical meter and control circuits and / or power circuits when a primary power source fails (e.g., when a primary power source is disrupted).

[0006] Various systems for generating and providing electrical power are described. Each system for generating and providing electrical power described herein can provide electrical power to a load (e.g., critical equipment) through an apparatus configured to securely attach to an electrical distribution component associated with the load, such as a fuse block. For example, the components of the apparatus can be configured (e.g., machined, etc.) with dimensions that complement / correspond to the fuse block and enable the apparatus to securely fit and / or attach to opposing conductive contacts (e.g., fuse contacts, etc.) of the fuse block. In some cases, the apparatus can be used for testing, measurement, and / or analysis. For example, the apparatus can securely fit and / or attach to opposing conductive contacts (e.g., fuse contacts, etc.) of the fuse block and / or associated components and interrupt electrical conduction through any of the opposing conductive contacts. Test, measurement, and / or analysis devices / components can be attached to the apparatus to perform testing, measurement, and / or analysis (e.g., voltage measurement, power measurement, frequency analysis, system impedance testing, etc.) on any components and / or devices, etc., attached to the non-interrupting conductive contacts.

[0021] 1A-1C illustrate an exemplary system 100 for providing power. As shown in FIG. 1A, system 100 includes a control module 102, a battery 104, a transfer switch 106, and an inverter 108. In the exemplary embodiment, system 100 is coupled to a cart 110 such that it is a portable system.

[0022] The control module 102 may have an input / output interface (I / O), an interface, one or more outputs 103, an auxiliary port, a switch, etc. The I / O may enable the control module 102 to communicate with one or more devices. The I / O may include any type of hardware suitable for communicating with a device. For example, the I / O may include direct connection interfaces such as Ethernet and Universal Serial Bus (USB), as well as wireless communications, including, but not limited to, Wi-Fi, Bluetooth, cellular, radio frequency (RF), etc. The control module 102 may provide power to its output 103. For example, the control module 102 may receive power from at least one of the transfer switch 106 and / or the inverter 108 and provide the received power to the output 103 to power one or more devices. As an example, one or more cables can be connected to output 103 to couple control module 102 to one or more devices, and control module 102 can provide power to one or more devices through one or more cables connected to output 103. Control module 102 can be removable from cart 110 and still continue to function. For example, control module 102 can be relocated to a location remote from cart 110 and coupled to system 100 through one or more cables (electrical connection 112c) coupled to control module 102.

[0023] Battery 104 may be one or more batteries configured to store power and provide further stored power. Battery 104 may provide DC power. Battery 104 may have an associated voltage, such as a 12V, 24V, 48V, 125V, 250V, 400V, etc. battery. Additionally, battery 104 may have an output current. For example, battery 104 may output 5A, 50A, 150A, 300A, etc. In an exemplary embodiment, battery 104 may be a 12V battery with a rated output of up to 150A. In another exemplary embodiment, battery 104 may be a 24V battery with a rated output of up to 300A. As will be appreciated by those skilled in the art, battery 104 may be a battery having any voltage and / or current characteristics.

[0024] The battery 104 can be any battery, such as a rechargeable battery or a non-rechargeable battery. The battery 104 can be a lithium-ion (Li+) battery, a lead-acid (Pb) battery, a lithium iron phosphate (LiFePo) battery, or any type of rechargeable battery. The battery 104 includes an auxiliary output. The auxiliary output can be capable of receiving DC power from another device and / or providing DC power to another device. For example, a device capable of operating on DC power can be coupled to the battery 104 to receive power from the battery 104. As an example, a light can be coupled to the battery 104. As another example, a device capable of providing DC power can be coupled to the battery 104. As an example, a maintenance battery charger can be coupled to the battery 104 to charge the battery 104.

[0025] The battery 104 may be one or more batteries configured to store power from the inverter 108. For example, the battery 104 may receive power from the inverter 108 through an electrical connection and store power from the inverter 108. In other words, the inverter 108 may charge the battery 104 through an electrical connection. Furthermore, the battery 104 may provide power to the inverter 108. For example, the battery 104 may discharge (e.g., provide power to) the inverter 108 through an electrical connection. Thus, the battery 104 has the function of receiving power from the inverter 108 as well as the function of providing power to the inverter 108.

[0026] The transfer switch 106 may comprise any switch capable of switching between two or more power sources. For example, the transfer switch 106 may receive power from a generator (not shown) coupled to the transfer switch 106 through one or more electrical connections 112a, 112b. The transfer switch 106 may provide the received power to the inverter 108 through the electrical connections. Alternatively, the transfer switch 106 may provide the received power to the control module 102 through the electrical connections. The transfer switch 106 may comprise an adjustable voltage verification time delay module. The adjustable voltage verification time delay module may be configured to variably set at least one of a voltage delay trigger or a time delay trigger when the presence of AC is detected on the electrical connections. That is, the adjustable voltage verification time delay module may be configured to set the voltage delay trigger after receiving power from the generator. The transfer switch 106 may provide power to the control module 102 after triggering the adjustable voltage verification time delay module. That is, the transfer switch 106 can provide power to the control module 102 through a different electrical connection while detecting power from the generator through an electrical connection.

[0027] The transfer switch 106 may have electrical connections 112a, 112b, 112c, 112d, and 112e capable of providing power to or receiving power from another device. For example, the electrical connections 112a, 112b, 112c, 112d, and 112e may provide power to or receive power from the control module 102, the battery 104, and / or the inverter 108. The electrical connections 112a, 112b, 112c, 112d, and 112e may be any suitable DC and / or AC electrical connections. For example, the electrical connection 112a may be configured to provide power to another device. As an example, the electrical connection 112a may provide power to an auxiliary device, such as a task light or another electrical device. In the exemplary embodiment, electrical connection 112a provides power to a power providing device (e.g., a power distribution hub) that facilitates providing AC and / or DC power to one or more other devices. Electrical connection 112b may be configured to receive power from a generator (not shown). Electrical connection 112c may be configured to provide power to control module 102. Electrical connections 112d and 112e may be configured to provide power to or receive power from inverter 108. Thus, transfer switch 106 may utilize electrical connections 112a, 112b, 112c, 112d, and 112e to provide power to or receive power from another device.

[0028] Additionally, the transfer switch 106 can receive power from the inverter 108. In an exemplary embodiment, the transfer switch 106 can switch between receiving power from the generator and the inverter 108. In other words, the transfer switch 106 can compete between the generator and the inverter 108. That is, the transfer switch 106 can automatically switch between the generator and the inverter 108. For example, when the generator runs out of fuel, the transfer switch 106 can switch to receiving power from the inverter 108, which is receiving power from the battery 104. In this way, the transfer switch 106 can continue to output power to the control module 102 even if one of its power sources (e.g., the generator, the battery 104) stops providing power to the transfer switch 106.

[0029] The inverter 108 may be any device capable of converting AC power to DC power and DC power to AC power. The inverter 108 may receive power from a generator through an electrical connection or may receive power from the transfer switch 106. For example, the inverter 108 may receive AC power directly from the generator or the transfer switch 106. The inverter 108 may provide the received AC power to the control module 102 through an electrical connection. The inverter 108 may convert the received AC power to DC power. The inverter 108 may provide (e.g., output) DC power to the battery 104 through an electrical connection. As an example, the inverter 108 may charge the battery 104 through an electrical connection. The inverter 108 may charge the battery 104 and simultaneously output, e.g., provide AC power to the control module 102. That is, the inverter 108 has the capability to charge the battery 104 and simultaneously provide power to the control module 102.

[0030] Additionally, the inverter 108 can receive DC power from the battery 104. For example, the inverter 108 can receive 12 VDC, 24 VDC, 48 VDC, 72 VDC, and voltages ranging from 100 VDC to 800 VDC. The inverter 108 can invert (e.g., convert) the received DC power to AC power. The inverter 108 can output inverted AC power. For example, the inverter 108 can output 110 VAC, 120 VAC, three-phase 208 VAC, three-phase 480 VAC, or any suitable output. The inverter 108 can provide inverted AC power to the control module 102 through an electrical connection. For example, the inverter 108 can include an internal transition switch. The internal transition switch can compete for AC power output to the control module 102 between two or more electrical inputs. For example, one electrical input can be a generator (not shown), and another electrical input can be provided by the battery 104. In other words, the inverter 108 has the ability to switch (e.g., automatically) between power inputs to maintain a constant output to the control module 102. The inverter 108 may have one or more indicators that indicate its status. For example, the inverter 108 may have one or more lights and / or displays that indicate its status. In an exemplary embodiment, the lights comprise light emitting diodes (LEDs).

[0031] FIG. 1B shows a front view of system 100. As shown, control module 102 includes outputs 103a and 103b, a plurality of switches 114, two displays 116a and 116b, and a control interface 118. Outputs 103a and 103b can output DC power and / or AC power. Outputs 103a and 103b can output the same or different types of power and the same or different amounts of power. For example, output 103a can be associated with a first power output (e.g., DC power and / or AC power), and output 103b can be associated with a second power output (e.g., DC power and / or AC power). As one example, output 103a can output a first DC voltage, and output 103b can output a second DC voltage. As another example, output 103a can output a first AC voltage, and output 103b can output a second AC voltage. As yet another example, output 103a may output a DC voltage and output 103b may output an AC voltage.

[0032] The switch 114 can switch the outputs provided by the control module 102. That is, the outputs 103a, 103b can be controlled by the switch 114. For example, the switch 114 can be associated with a breaker that determines whether the control module 102 provides power to the outputs 103a, 103b. As an example, the switch 114 can be individually flipped to control the outputs 103a, 103b such that the output of the control module 102 can be modified based on the position of the switch 114. Furthermore, one of the switches 114 can be a power switch that switches the control module 102 between an off state and an on state.

[0033] The control module 102 may have two displays 116a, 116b. The two displays 116a, 116b may indicate the status of the control module 102. For example, the two displays 116a, 116b may indicate the outputs of the control module 102. As an example, the two displays 116a, 116b may be associated with particular outputs of the control module 102 and may indicate the voltage and current currently being provided by each output.

[0034] The control module 102 may include a control interface 118. The control interface 118 may have any function for controlling the operation of the inverter 108. For example, the control interface 118 may control the power provided to the inverter 108. That is, the control interface 118 may have the function of turning the inverter 108 on and off. The control interface 118 may indicate the status of the inverter 108. For example, the control interface 118 may indicate whether the inverter 108 is receiving power from the battery 104 or a generator (not shown). As another example, the control interface 118 may indicate whether the battery 104 is being charged by power provided by the generator through the transfer switch 106. The control interface 118 may indicate the operation of the inverter 108. For example, the control interface 118 may instruct the inverter 108 to draw power from the battery 104 rather than the generator. Similarly, the control interface 118 may instruct the inverter 108 to draw power from the generator rather than the battery 104. Although the control interface 118 has been described as controlling the operation of the inverter, those skilled in the art will recognize that the control interface 118 may also have the functionality to control the operation of the control module 102, the battery 104, and / or the transfer switch 106.

[0035] FIG. 1C illustrates a side view of the system 100. Specifically, FIG. 1C illustrates electrical connections 112a, 112b, 112c, 112d, 112e, and 112f between the control module 102, the battery 104, the transfer switch 106, and the inverter 108. As shown, the transfer switch 106 is coupled to the inverter 108 through electrical connections 112e and 112d. Additionally, the control module 102 is coupled to the transfer switch 106 through a single electrical connection 112c. Similarly, the battery 104 is coupled to the transfer switch 106 through a single electrical connection 112f.

[0036] 2 illustrates an exemplary system 200 for providing electrical power. As shown, system 200 includes a generator 202, an inverter 204, a battery 206, and a power distribution hub 208. System 200 further includes an apparatus 250. Apparatus 250 may include inverter 204 and battery 206. Apparatus 250 may further include any of the components of system 200. For example, apparatus 250 may include cart 110 of FIGS. 1A-1C. In the exemplary embodiment, each of the components of system 200 is a separate device that is not enclosed within an apparatus.

[0037] The generator 202 may be any generator capable of providing electrical power. For example, the generator 202 may be capable of alternating current (AC). The generator 202 may output voltages between 100 VAC and 250 VAC and higher. For example, the generator 202 may output 120 VAC and / or 240 VAC. The generator 202 may operate on any suitable fuel, such as gasoline, diesel fuel, liquefied petroleum gas (LPG), natural gas, and the like. The generator 202 may operate on two or more fuels. For example, the generator 202 may be capable of operating on both gasoline and LPG. The generator 202 may be capable of switching between the two fuels, either manually or automatically. As one example, the generator 202 may default to running on gasoline stored in a gasoline tank associated with it. The generator 202 may switch to LPG when the gasoline in the gasoline tank is depleted. As another example, the generator 202 may switch between two or more LPG tanks coupled to it. That is, when the LPG in a first of the two or more LPG tanks is depleted, generator 202 can manually or automatically switch to a second of the two or more LPG tanks. Generator 202 can provide (e.g., output) electrical power to inverter 204 through electrical connection 220. For example, generator 202 can provide AC power to inverter 204 through electrical connection 220. Furthermore, generator 202 can provide electrical power to distribution hub 208 through electrical connection 220 and electrical connection 226. Stated another way, generator 202 can bypass inverter 204 and provide electrical power directly to distribution hub 208.

[0038] The inverter 204 may be any device capable of converting AC power to DC power and DC power to AC power. For example, the inverter 204 may be a rectifier. The inverter 204 may receive power from the generator 202 through the electrical connection 222. For example, the inverter 204 may receive AC power from the generator 202 through the electrical connection 222. The inverter 204 may provide the received AC power to the power distribution hub 208 through the electrical connection 226. The inverter 204 may convert the received AC power to DC power. The inverter 204 may provide (e.g., output) the DC power to the battery 206 through the electrical connection 224. As an example, the inverter 204 may charge the battery 206 through the electrical connection 224. The inverter 204 may charge the battery 206 and simultaneously provide AC power to the power distribution hub 208. That is, the inverter 204 has the function of charging the battery 206 and simultaneously providing power to the power distribution hub 208 .

[0039] Additionally, inverter 204 can receive DC power from battery 206. For example, inverter 204 can receive 12 VDC, 24 VDC, 48 VDC, 72 VDC, and voltages ranging from 100 VDC to 800 VDC. Inverter 204 can invert (e.g., convert) the received DC power to AC power. Inverter 204 can output inverted AC power. For example, inverter 204 can output 110 VAC, 120 VAC, three-phase 208 VAC, three-phase 480 VAC, or any suitable output. Inverter 204 can provide inverted AC power to power distribution hub 208 through electrical connection 224. For example, inverter 204 can include an internal transition switch.

For example, the DC-AC inverters 914a, 914b can receive voltages ranging from 12 VDC, 24 VDC, 48 VDC, 72 VDC, and 100 VDC to 800 VDC. The DC-AC inverters 914a, 914b can invert (e.g., convert) the received DC power to AC power. The DC-AC inverters 914a, 914b can output inverted AC power. For example, the DC-AC inverters 914a, 914b can output inverted AC power. For example, the DC-AC inverters 914a, 914b can output AC power between 0 and 800 VAC, or any suitable output.

[0110] For ease of explanation, electrical connections 920-940 are generally shown as direct connections between the various components of system 900, but those skilled in the art will recognize that electrical connections 920-940 may include additional components such as resistors, capacitors, inductors, breakers, switches, and the like.

[0111] Figure 10 illustrates an example system 1000 for providing electrical power. Specifically, as described in more detail below, system 1000 is the same as system 900 of Figure 9 except that power distribution device 1002 comprises the functionality of variable frequency drive 916 of Figure 9.

[0112] The power distribution device 1002 can be any device capable of distributing power. Specifically, the power distribution device 1002 can receive power from AC-DC converters 906a, 906b and provide the received power to a battery 910, step-down transformers 912a, 912b, DC-AC inverters 914a, 914b, and / or a variable frequency drive 916. The power distribution device 1002 can receive power from a generator 902 and / or a three-phase power source 904 through the AC-DC converters 906a, 906b. The power distribution device 1002 can receive voltages ranging from 12 VDC, 24 VDC, 48 VDC, 72 VDC, and 100 VDC to 800 VDC. For example, power distribution device 1002 can receive DC power from AC-DC converter 906a through electrical connection 922 and can also receive DC power from AC-DC converter 906b through electrical connection 926. Power distribution device 1002 can provide (e.g., output) DC power to battery 910 through electrical connection 928. As an example, power distribution device 1002 can charge battery 910 through electrical connection 928. Power distribution device 1002 can charge battery 910 and simultaneously provide power to one or more additional devices. For example, power distribution device 1002 can provide power to step-down transformers 912a, 912b and DC-AC inverters 914a, 914b while simultaneously charging battery 910.

[0113] Additionally, the power distribution device 1002 can receive DC power from the battery 910. For example, the power distribution device 1002 can receive voltages ranging from 12 VDC, 24 VDC, 48 VDC, 72 VDC, and 100 VDC to 800 VDC. The power distribution device 1002 can invert (e.g., convert) the received DC power to AC power. That is, the power distribution device 1002 can invert DC power received from the battery 910 and the AC-DC converters 906a, 906b. The power distribution device 1002 can output inverted AC power. For example, the power distribution device 1002 can output an AC output of 110 VAC, 120 VAC, or any suitable output. The power distribution device 1002 can provide the inverted AC power to the transfer switch 1016 through an electrical connection 1020. The power distribution device 1002 can include an internal transfer switch. The internal transition switch may be capable of competing between DC power received from electrical connection 922 (e.g., provided by AC-DC converter 906a), DC power received from electrical connection 926 (e.g., provided by AC-DC converter 906b), and DC power received from electrical connection 928 (e.g., provided by battery 910). In other words, power distribution device 908 is capable of switching (e.g., automatically) between the power input received from AC-DC converter 906a through electrical connection 922, the power input received from AC-DC converter 906b through electrical connection 926, and the power input received from battery 910 through electrical connection 928 in order to maintain a constant output to transition switch 1016 through electrical connection 1020. Power distribution device 1002 may have one or more indicators to indicate its status. For example, power distribution device 1002 may have one or more lights and / or displays that indicate its status. In an exemplary embodiment, the lights comprise light emitting diodes (LEDs).

[0114] Power distribution device 1002 may be capable of outputting three-phase AC power. That is, power distribution device 1002 may invert incoming DC power into AC power, convert the inverted AC power to three-phase AC power, and output the three-phase AC power to transfer switch 1016 through electrical connection 1020. Power distribution device 1002 may provide three-phase AC power between 0 and 480 VAC. The operation of power distribution device 1002 may be modified through programming. For example, the ramp rate of power distribution device 1002 may be modified, as well as the terminal voltage of power distribution device 1002.

[0115] For ease of explanation, electrical connections 1020-1038 are generally shown as direct connections between the various components of system 1000, but those skilled in the art will recognize that electrical connections 1020-1038 may include additional components such as resistors, capacitors, inductors, breakers, switches, and the like.

The power transfer device 1103 can include a conductive base 1104. The conductive base 1104 can comprise (be constructed / machined of) a conductive material. For example, the conductive material can comprise silver, copper, gold, and / or any other conductive metal / material.

[0118] The conductive base 1104 can include mounting element 1105 and / or mounting element 1106. The conductive base 1104 can include any number of mounting elements.

For example, the non-conductive material can include a fiberglass-epoxy laminate (e.g., Gallolite, etc.) and / or any other non-conductive material. The non-conductive member 1108 can, for example, prevent and / or inhibit power transferred to the power transfer device 1103 from being fed back to a source such as the power distribution module 1101.

[0121] In some cases, the power transfer device 1103 can be configured (e.g., machined, configured, etc.) in a shape, such as a cylindrical shape, a cartridge fuse shape, and / or a power distribution fuse shape.

The non-conductive member 1108 can prevent and / or inhibit power transferred to the power transfer device 1103 from being fed back to the source (the power distribution module 1101), etc., and can block / prevent power from being transferred to the conductive contact 1111 of the industrial fuse box 1109. The conductive contacts 1111 may be connected (electrically coupled) to a power source that has stopped / failed, such as a power source that normally provides power to a load.

[0123] In some cases, the power transfer device 1103 can be used for testing, measurement, and / or analysis, such as voltage measurement, power measurement, frequency analysis, and / or system / component impedance testing. For example, the power distribution module 1101 can be disconnected from the power distribution module 1101, and the power transfer device 1103 can be electrically coupled and / or connected between the output of a test, measurement, and / or analysis device and / or component, such as a multimeter, oscilloscope, and / or diagnostic device.
